Apart from the skills mentioned above, the developer should also keep up with the current trends. Most companies now build applications and services with features and implementation of Artificial Intelligence and Data Science.
Let's have a look at different fields where Java is extensively used.
A. Mobile App Development
Many popular mobile applications, such as Spotify, Twitter, are developed using Java. It has been the go-to language for years. Although it might not be used in IOS development, it is beneficial when working with android studio.
Android studio: It is the official IDE (Integrated Development Environment) for the android operating system designed specifically for Android development. It gives you a development environment and access to android development tools such as SDK tools. It supports all the programming languages of Intellij, such as Java, Kotlin, C++, Go, etc.
Emulator: It is the most important and beneficial tool to test and debug mobile applications during development. It simulates a mobile environment on the PC. Other than the emulator provided by Android Studio, there are many other popular choices like vMac, NoxPlayer, Dolphin, etc.
User Interface (UI) design: It is essentially important in start-ups that do not have a professional UI designer in the team. The UI design must be user-friendly, attractive and handy.
Apart from these skills, there are many more such as getting APIs, handling and parsing XML, etc., but these should get you started.
B. Web Development
Java has mostly been used as the backend of a web application or on the server-side applications. A web developer is expected to 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, such as:
Apache Tomcat is the most famous implementation of Java Servlets and JavaServer Pages, which has been a common choice to run applications on a server.
C. Desktop GUI Application
Java has become a handy tool for Desktop Application Development since the Swing toolkit is gaining popularity. For this field, one has to get skilled at making widgets with the tools like Swing GUI toolkit developed by JavaFX and Oracle. Both of them use AWT (Abstract Window Toolkit), available in the Java Development Kit (JDK), to build cross-platform applications.
To build Desktop Applications, you could also use SWT (Standard Widget Toolkit), a programming library developed by IBM. These days developers use SWT with Eclipse RCP to build Desktop GUI Applications.
D. Enterprise application
Enterprise applications are used to organize and model business processes for organizations. And the core tool used in developing enterprise software using Java is Java EE or Java Platform, Enterprise Edition. The need for enterprise software increases as new companies adopts the DevOps culture to increase efficiency.
Many legendary games like Revenge of the Titans and Spiral Knights are developed in Java. Minecraft's original version is also written in Java, a very well-known game all over the globe.
Java has excellent career opportunities in the rising gaming environment. Java helps build a cross-platform version of the game without extra development costs and hence, is an excellent choice for building games. When it comes to building 2D games on Android, Java is the foremost choice.
And for this, familiarity with the physics involved in game development and building multi-threaded applications using Java is necessary. Getting to know how the new versions of JVM help improve garbage collection comes in real handy. Java persists despite the rising popularity of game engines like Unity and Unreal.
F. Scientific Applications
A developer's first choice is Java for building applications designed to carry out several mathematical operations and scientific calculations. Java's fast computing and processing speed make it the developer's first choice. MATLAB, a commonly used computing environment's UI, is also written in Java.
To build a complete scientific application in Java, use Java with the CUDA toolkit to support GPU computing (an important feature to carry out huge amounts of scientific computations). The Rootbeer GPU compiler should help you with that.
