Mobile App Development
Java has been the go-to language for years in this field. Although it might not be of much use in IOS development, it is beneficial when working with android studio.
That being said, the additional skills required, apart from java basics, are:
- Android Studio: This is the official IDE (integrated development environment) for the android operating system. It gives you a development environment and access to android development tools (SDK tools). It supports Java, Kotlin, and C++. It provides quick fixes that facilitate addressing issues associated with categories, performance, security, etc.
- Emulator: This is important to test and debug your mobile applications during development. It is used to simulate a mobile environment inside a PC. Although Android Studio does provide an emulator extension with it, there are many other popular choices like vMac, NoxPlayer, Dolphin, etc. Different operating systems can be run using an emulator. The developers can work around various interfaces to get the experience of a mobile device. It is a safe medium for testing codes.
- User Interface(UI) design: Although this is not of much use for a senior developer who probably has a UI designer in their team, it is a necessary skill when you are just starting out or working for a startup. You only need to know the basics. It is very important to know UI as it aids in meeting the user expectations and yet meeting the optimum site functionality. It is an important feature as it communicates clearly to the user about the company’s products, vision and mission.
There are many more skills like getting APIs, handling and parsing XML, etc. but these should get you started.

Java has often been used on the server side or the backend of a web application.
Getting into web development, every developer must know the basics of HTML, CSS, and APIs.
But, to build a java web application, you must get used to a few dynamic resources and tools that java provides like:
- Servlets: A Java class that is used to handle HTTP requests. It gives better performance, as it creates threads for each request. It is portable because it uses Java. Most importantly, it is scalable; once deployed, it can instantly start fulfilling the client’s demands.
- JavaServer Pages: This is a way of writing Java code with HTML for fast production. It is majorly used for building robust web pages that connect to the java backend. JSP aids in writing and developing dynamic web pages. Along with the dynamic part being written in Java, it serves another important purpose, and that is being portable to other operating systems and non-Microsoft web servers.
- Jars: This is used for the aggregation of files and metadata into one file
The most famous implementation of Java Servlets and JavaServer Pages is Apache Tomcat which has, for a long, been a common choice to run applications on a server.
Desktop GUI Application
With the Swing toolkit gaining popularity, Java has also become a handy tool for Desktop Application development.
For this field, you will have to get skilled at making widgets with the tools like the Swing GUI toolkit that was developed by Oracle and JavaFX. Both use AWT (Abstract Window Toolkit), which is available in the Java Development Kit(JDK) to build cross-platform applications.
You could also use SWT (Standard Widget Toolkit), which is a programming library developed by IBM to build Desktop Applications.
Nowadays, developers use SWT with Eclipse RCP to build Desktop GUI Applications.
There are various benefits to Desktop GUI Application, such as its easy-to-use benefit, with the presence of symbols, shapes and icons the users can easily recognise and navigate through options. It is also advantageous in communicating better as the visuals are understood faster than the texts. It is widely accepted because it allows users to communicate better with the presence of visual components.

The need for enterprise software is increasing as new companies move towards adopting the DevOps culture to increase efficiency.
There are various benefits attached to enterprise applications, such as control of the company. An enterprise application can give full control of the company owing to the information management. The overall vision can be communicated which makes it possible to procure the full knowledge of the ongoing.
It aids in reducing costs and investments and in simplifying the process. Additionally, the information can be exchanged much more easily reducing the chances of duplication and increasing communication transparency.
Did you know that the original version of Minecraft is written in Java? Other legendary games like Revenge of the Titans and Spiral Knights are also developed in Java.
Java is an excellent choice for building games as it helps to build a cross-platform version of the game without extra development costs. Java is also the first choice to build 2D games on Android. With the rising demands in gaming, there are excellent Java career opportunities.
For this, you should be familiar with the physics involved in game development and get used to building multi-threaded applications using Java. Getting to know how the new versions of JVM help improve garbage collection also comes in handy.
Java serves a huge role in the game industry and for the same reason, there is a demand for java developer jobs. It is used for developing games for both servers and mobile devices.
Language versatility and open-source material are contributing factors behind its vast acceptability. Socket programming allows the developers to link between two processes.
Additionally, various games can be developed using Java as a programming language, such as mobile games, Indie games, and AAA games.
Even with the rising popularity of game engines like Unity and Unreal, Java is still here to stay.
Java is the favourite choice for developers when building applications designed to carry out scientific calculations and a number of mathematical operations. This is mainly because applications built with Java have fast computing and processing speeds. The UI of the commonly used computing environment, MATLAB, is written in Java.
To build a complete scientific application in Java, you must be familiar with using Java with the CUDA toolkit to support GPU computing (which is an important feature to carry out huge amounts of scientific computations). The Rootbeer GPU compiler should help you with that.
In today’s work environment, a developer does not become work-ready only with technical skills. They also have to be proficient in soft skills. This not only helps them perform better in interviews but also increases efficiency at work. Most companies now also consider soft skills when hiring new developers.

Java: Growing popularity and current market trend
Java is one of the old programming languages that have done well to deliver with the changing demands of the market. According to newrelic.com, Java 8 is currently the most accepted version of Java in the market, with Oracle being the dominant vendor and maintainer of the Java language as well as the Java Virtual Machine (JVM), since the acquisition of Sun Microsystems in 2010.
Even after being declared the most popular programming language of 2019, some say that Java is losing its charm to trending languages like python. But even the most contradicting arguments from trusted sources give the following reports.
Even this gives us the impression that Java is not a language that is going away anytime soon. As it is safe, portable, comes with a higher level of concurrency tools, is maintainable and serves a purpose in various important industries.
Moreover, to get a better idea of the popularity of java as a programming language, let us look at the trends of its Tiobe index. Tiobe index is a measure of the popularity of the programming language that is measured after considering factors like market share, number of job postings, open-source projects, etc.

The income of a freelance developer varies depending on different factors like region, type of clients, experience, etc. It also sometimes depends on the platform on which the freelancer meets clients. Overall, there are freelancers who do this as a side income and many who do this full time as well. But as a freelancer, one must be outgoing and network as much as one can, either the offline events or professional networking sites. Additionally, the freelancers must create a trustable factor of their own with the presence of their website, blogs, etc. Apart from the technical skillsets, one skill set holds s highest importance, and that is time management; a freelancer must be able to manage their time and tasks to meet the deadline and maintain a good reputation in the market.
