10 Skills to Become an Expert Java Developer in 2020

Have you learned anything new yet this year? I’m sure with the evolving technologies, there are lots to catch up with. Talking about technologies, do you know that java has brought plenty of changes? And it will get tough if you are not up to date. Don’t worry if you have not updated your data of java you are in the right place.

I am sure many mobile app development companies have managed to keep up to date with the latest technologies. If not this blog helps you to know the list of things developers should learn in 2020.

What is Java

Before jumping into new trends of java, let’s quickly get a brief idea about what is Java? Java is the most common programming language for Android smartphone applications. The major benefit of java is “write once, run anywhere”. This says that compiled Java code can be run on all java supported platforms without the need for recompilation. Its automatic garbage collection mechanism makes it even more popular. Being one of the most preferred programming languages for edge device creation and the internet of things. Java is used in a vast domain-like Banking, retail, information technology, android, stock market, big data, scientific and research community, etc

Here we are going to elaborate on new skills that can help you become a java expert in 2020. 


If you are trying to get better on java, make sure to go for DevOps. DevOps is an IT mindset that allows software developers and IT developers to collaborate, work together, integrate and automate to improve software quality and speed. It also helps to improve the cooperation between all stakeholders from planning, implementation, and automation to others.

  • Improvement of deployment frequency
  • To achieve faster time to market
  • To lower the failure rate of the new release
  • It also shortens the lead time between fixes
  • Improve mean time to recovery


Well, developers, do you know that lately, Github has been around. And most businesses now move from SVN, CVS to Git their programs, as it provides fast performance, convenient & has multiple workflows. Anyhow, If you want to use Git from a Java application, there is a full-function library named JGit. You can branch and merge with Git any time, and it boots fast. Now, Developers can get complete control over the local code base and be able to handle changes offline. 

This means things you can do like;

  • Frictionless context switching
  • Role-based code lines
  • Features based workflows
  • Disposable experimentation

Docker and Kubernetes

Well you probably have heard the buzz Of IT town about dockers and Kubernetes and its impact on DevOps. Dockers are not just a new technology but it’s a game-changer in the field of development. Today almost all development teams, be it a big company, small startup, or an android app development company use Docker and Kubernetes. Docker containers will help you isolate and load your apps in full. whereas Kubernetes will help you deploy your containers and arrange them. This helps you to concentrate more easily on creating new features and fixing bugs. 


The architecture of microservices ensures the fast, frequent and consistent delivery of massive, complex applications. Microservices also helps an organization build its stack of technology. 

It structures an application as a collection of service that is:

  • Highly maintainable and testable 
  • Loosely coupled 
  • Owned by a small team 
  • Organized under business capabilities 
  •  Independently deployable.

Spring Framework 5

If you haven’t tried spring framework5, it’s the right time. Spring is a system that allows you to “wire” different components. It’s useful when you have several components and you may want to combine them in various ways. And to make it simple if you want to switch one part into another in conjunction with different settings or environments. 

Unit Testings

It is a software testing standard in which individual units/software components are evaluated.  The goal is to validate the output of every unit of the program. The smallest part of any device can be checked. Mainly it has one or more inputs and typically only one output.  There are 3 types of testing like Black box testings, white box testings, and grey box testings.

Spring security 5.0

Spring Security is an authentication, authorization and security mechanism against specific attacks. It is the de-facto standard for Spring-based applications with first-class support for both imperative and reactive applications. 

Cloud ( AWS)

Besides containers, Cloud is something all software developers are expected to learn in 2020. Firms from all sizes and sectors are now shifting their infrastructure to Cloud to save money and to boost scalability. It means that you will need to deal with cloud-based applications sooner or later. Cloud computing is the on-demand provision by the pay-as-you-go price of IT services over the internet. You can get access to technology resources like computing power, storage, and databases on the necessary basis from a cloud provider. 


Currency ensures that several transactions exist simultaneously. If the processor assigns two processes to separate machine cores, and the processor instructions are executed concurrently by both cores. 

RESTful Web Service

REST is used to create lightweight, maintainable and scalable Web services. A RESTful Server is a database designed on the REST architecture. The REST protocol is based on HTTP & the standard web protocol. 


Thanks for being patient and reading this blog. Every day we come up with new technologies and it’s very important to keep updating ourselves with new technologies. Anyhow currently for java developers and mobile app service providers, the upper mention technologies are there to look out for 2020.  I hope this technology interests you & you would probably be thinking of involving upper mention technologies on your new project.

Art of Minimalism in Mobile Apps

Art of Minimalism in Mobile Apps

With the art of app designing taking a more aesthetic approach, designing the UI in a way users will perceive as something simple and satisfying has become more significant than anything. Today, building a minimal UI has not only become vitally important but necessary to engage an ever-growing audience. The skeuomorphic way had its share of days when people loved to see lots of elements and a play of different designs encapsulating a variety of information. Now the scenario has changed. As you already have several million established apps, it’s important to make the path to your minimalistic mobile UI clear and simple for the users. The only basis that user’s judge your app is by gauging the minimalistic app design which provides a clear, informative and straightforward prism for them. You only need to figure out two important things before you head on to inculcate minimalism in mobile apps. First is form. Second is function. If you nail this part, your app design will have a minimalist mobile UI.

Minimalism is the key

When we talk about minimalist mobile UI or minimalist apps, we have to understand the essential aspects that form the underlying foundation of minimalistic app design. It’s vital that you use relevant information and ultra-important that you use bare minimum graphics elements. If you bombard it with information and clutter it with too many elements, your app will more likely be perceived as desperate rather than an aesthetic, and a minimalistic app design.

What are those minimalist UI design principles that result in a minimalist app? Let’s walk through them.

Color is the apex

Minimal Color - Parangat
Minimal Color

You have to maintain a color scheme that represents your brand or business and stands as a symbol for it. You cannot have a blue color scheme today and change the color scheme to yellow tomorrow. Colors leave a subconscious effect, making a user connect to a UI, and it works. It is precisely why different users choose different apps as per their preference. You have to select a minimalistic color scheme for your minimalistic app design and provide a common plug point for both your brand and users to achieve higher UX. You can use Simplistic color schemes like Monochromatic color schemes or Analogous color schemes for minimalism in mobile apps. You can also use a specific and vibrant color to emphasize some vital information or primary elements in the app.

Typography for connection

Do not jumble different typefaces

Chaos is not a ladder, my friend. When you sit down to figure out how to epitomize the art of minimalism in mobile apps, you will have to decide one typeface for your communication. Period! If you use different fonts for different sections of communication, the chaos ladder will fall on you and wreak havoc on your minimalistic app design. To get more understanding on this, you can go through different mobile UI design examples which used single typeface and communicated better than those chose to have different fonts inside the app. Choose one standard typeface according to iOS or Android. Stress on important information with better use of typography.

A play of whitespace and shadows

A play of whitespace and shadows is always great!

According to Medium, use of white space where you don’t place any content is considered to be the backbone of minimalistic app designs. And this is a worldwide accepted practice of minimalism in mobile apps these days. You can use vertical and horizontal lines, placing them with enough whitespace in between so that you give visual clarity. You can also use elevation and shadows to make some information or element evident. It is no doubt that there is no perfect minimalist mobile UI design out there. But eventually, you can hit the right node if you keep it simple and effective.

Icons work like a miracle

Keep the icon simple and noticeable

You can have the most simple icon in your minimalistic app design and yet achieve seamless interaction and perfect deliverance of communication. But don’t get it wrong. We are not asking you to draw stick figures. You can have an ideal icon that helps the user in navigation without the icon being overly graphic which makes it very complex. A user runs his eyes throughout the interface within a fraction of seconds. It is essential for you to harvest this attention using effective icons for primary functions. You can use both solid and hollow icons for incorporating minimalism in mobile app.

Finding minimal UI design inspiration has become easy today. As developers and UI designers both invest efforts in perceiving app designing from psychoanalytic and scientific behavioral standpoints, you get substantial information on user behavior. And this has lead to the art of minimalism in mobile apps being no rocket science today. It’s just emphasizing on relevant, valuable information and designing accordingly. Some of the many minimalist app design inspiration includes apps like

  • Minimalist Habit by Hasan Yavaş
  • Forest App by Shaokin Pi and Amy Jeng
  • Tenant Management by Johny Vino

All these apps have minimalist mobile UI. They tend to be perfect mobile UI design examples who inculcated minimalism in mobile apps, and their popularity is proof of creating a successful minimalistic app design. As we have elucidated above, skeuomorphic mobile UI design examples like Paper iPad App, Timer App, National Geographic National Parks App, and many others seem to have worked in the past. But today, we only see minimalism in mobile apps as the underlying aesthetic philosophy that defines a successful UI design with notably higher UX.

Go minimal!

A Good App Design Means Good Sales

A Good App Design Means Good Sales

The journey from the drawing board to converting each click in your app into money involves thought. It is no mumbo-jumbo game. For your app design to reach the mark of success and generate success both from UX and sales perspectives, it needs to have a well thought and developed app design. A good mobile app design ties back to the designing of a user interface and how easily an individual can access and use it making him/her return to your app.

Right from the moment a person opens your app to the moment of clicking ‘BUY,’ everything has to be thought of! Especially when it comes to e-commerce apps, you have a roller coaster of sales involved which is directly affected by your app’ design practices. Less effective buttons and a poor user interface is a massive cause in poor sales or conversion in most mobile apps. Designers need to put yourself in the shoes of the user and think like them. The very fact that they choose your mobile app over the physical store over any day is simple! You get them what they need without complications which in turn boosts your sales through your mobile app.

Effective App Design - Parangat

Some of the best e-commerce app design has boosted their sales with unbelievably simple tactics like the simplicity of their apps or adding a visible Call-to-Action button or enhanced flow of navigation. It is irrefutably vital for you to adhere to some pillars that lets you build the best mobile app design for e-commerce. According to jmango360, Amazon has got one of the best e-commerce app design because of its intelligent use of simplicity and one-click navigation. It is difficult for Amazon as a giant in retail to mark this position in app design, but somehow they seem to play the game well! Let’s see some of those pillars that you should induce to your app design to make it user-worthy.

Good & Bad Call-to-Action Button - Parangat

Before we move on to that, let’s see some examples of UX design/redesign that helped them increase sales.

  • Walmart (Retail Shopping) – A tremendous upswing of 214% in traffic after it redesigned the user interface for better functioning and easy navigation.  
  • Anthropologie (Clothing retail) – Saw a boost in sales by 24% by redesigning an easier and faster checkout process.
  • Bank of America – Marked a rise of 45% after the same.

All of them followed this-

Cohere to their journey

It is essential for mobile app designs to be thoughtful and maintain flow in users app journey.  The flow of the journey should be so smoothly inclined with users that even a click on button or link should not feel different from them. Now that is significant to give any user an excellent reason to come back to the app.

Make it Easy for them

Minimalism is the key! Bombarding your app with too many options and things would work against UX. A vast amount of sales rests with how easy your in-app journey is. Keep your content minimum and make the journey effortless so that they can proceed to the payment checkout process faster in your app. With many of the food delivery app design that we see today, the problem lies in a single aspect. And that is offers and discounts. Before a user can proceed by adding food to their cart, they are bombarded with more offers to consume more. It creates obstacles to faster checkouts. The more balanced apps out there drive their users to payment shores without adding layers to it.

Easy to Use App Design - Parangat

Fast, but not furious!

This point throws the dart to how fast and robust your app design should be. To provide a positive UX, your mobile design for e-commerce app should be quick in response with the support of robust servers. Failing to do so will clonk you with an app design that is fast but prone to crashes. You also need to bring in the art of keeping it minimal here as cluttering your app would further bog down the pace. Right from the drawing board, determine what is needed! Then hop on to designing it for much visual clarity and pleasure of using the app.

Play visually and keep it attractive

The best part about food app designs is the visual attraction. Apart from the fact that the content of food naturally makes it attractive, the designers of these apps incorporate impressive color schemes that compliment the food. If you want to find some food app design inspiration, you should probably check the Healthy Food App designed by Ernest Asanov. The success of this app revolves around the visual color schemes it uses to compliment the delicacy or recipe of any particular food item it talks about.

Visually Attractive App Design - Parangat

There has been a tremendous rise in food apps as more and more restaurants are plunging into new and easier ways of selling food. With more brilliant restaurant app UI designs, the world is seeing several food apps like  Tasty Burger App, Food Parlour, Kitchen Stories, NomNom and many more.

The mobile app design for e-commerce has also seen a fantastic rise as app designs have belly flopped into the digital dimension with new found ways to improve their UI and UX. And as more and more apps are being resurrected to see a new dawn in e-commerce, we also see a rise in developing and UX designing ideas which, is going to see a new height soon.

Typography Best Practices in Mobile App Design

Typography Best Practices in Mobile App Design

Written copy never dies. No matter how engaging or how creative your visuals are, people still need information by text. It is imperative that your app design needs to have well thought and persuasive written text which will deliver your message across. It is the art of typography in mobile app design. It is perennially considered to be the most crucial aspect of mobile app design. The small screen of your app should be treated as your canvas to speak to the world. Now there are better and best practices to design your font in typography. We talk about only the best practices of typography in here. Whenever you scratch your head with the question ‘How to do typography in mobile?’, this list will help you!

Should be Readable (Legibility)

The font of your written information should be legible. Period! First comes determining what the message is. Then the presentation of it. As mobile screens tend to be small (even though it’s a battle out there to launch bigger display) your app has to have a readable font. With icons, buttons, links, images, and content, lousy app design always land up in a wrestle between them. Your designing team should hail CLARITY as the most vital aspect of mobile typography best practices. It should be clear, effortless and striking!

Appropriate Leading

Line spacing is critical. Often it becomes evident to writers that your entire written data won’t work if it’s not presented neatly with proper space and width. Now designers should cogitate about the same with their app design. This factor decides how a user reads a text and the success of the flow of it. The primary copy should be big enough to catch attention, the lines that follow should be smaller making it easy for the eye to flow through the information. It should be practiced for mobile website topography too, not just your app.  

Express with Fonts

We have different fonts to express diversely. The perfect balance between creative and unanimous font should be achieved. You should not go overboard with creativity or even make it monotonous. You should use the best fonts for mobile UI and UX. Expressing is not just limited to art or color schemes of the app. The overall theme or message can be forged into the written content provided you design your typography the way you want to express. Font style and size should be designed to match the entire theme of the app design. Looking like a theme far fetched from different worlds will result in a disaster. Your app. One world. This is it!

Minimalism and Simplicity

Before moving on to any other aesthetics, the designer should be clear about what he/she wants to say! Then comes phrasing it minimally and simply, which is a significant aesthetic aspect even for app layout and design. Using fancy or decorative fonts may prove to be overwhelming as small screens have their limitations within which you have to apply colors, shades, geometry, buttons and other elements. It is precisely why a simple yet powerful font is advocated as a best practice of font size. It will help you achieve better and greater UX.

Let your Canvas Breathe

The canvas of your app; the layout, should breathe and let users perceive your font and written text without a hitch. If your font size and style is essential, the white space of the canvas is super important! If you bombard the layout and cringe in several texts and font styles in desperation, users will reject your app because you are making it difficult for them to navigate inside your mobile app. And many designers and developers does this mistake, that too in style! Keeping enough white space between texts, visuals, buttons, and all the other elements is one of the most fundamental practices of typography in mobile.

Device-centric Typography

If you look at Apple devices, their app designers inscribe the font in Helvetica Neue, which is the best font for ios app design. They use that for every device. It works splendidly for them! To achieve similar UX for your mobile app, typography should be thought through. Right from smartphones to tablets, or even smartwatches for that matter, the typography of your app design should suit every device. Your font should be unanimous, and the size of it should match the different screen sizes that span across users.

If your mobile app is all in to achieve a higher and positive UX, creating a beautiful app with the best typography in mobile app design is quintessential. The aesthetics of what makes your typography in the mobile app beautiful cannot be debated. The above mentioned are some of the many practices to achieve the best typography for your app.

Pouring in a lot of steps and actions for the user side will create unwanted complexity ultimately leading to confusion, which then results in uninstallation or deletion. During the development cycle, designers and developers should learn from both apps that have seen failure and success. Ensuring the flow and pace of the UX is critical. Considering thumb behaviors and finger tap controls will get your app the momentum it wants. The payment procedure of an e-commerce app are thoughtful and have chunked down multiple steps to just 3-4 simple steps.

You might have expertise on what will please UX more, but you will miss those infinitesimal things that could be the breakthrough for your mobile app. These responses and criticisms serve as your mobile app design inspiration to enhance your app at every stage of UX.

Customer Feedbacks Ratings - Parangat

Decluttering the app at every stage

An app contains a lot of information. Right from every written word to icons in the app, everything is information. Exactly why it needs to be minimal and allow users to breathe. Without that, UX is almost dead. Developers need to continually refuel the app with relevant information and updates which is required. It’s true that a brand can manage a lot inside an app with their resources. But it’s different on the other side. In the first stage itself, you should not clutter your apps with a tsunami of icons and information which leads to perplexity. And at every stage of app development and upgrade, as a designer and developer, you should consider infusing fresh feedbacks and declutter outdated information ultimately leading you to new mobile app designing ideas.
