Application of Java Programming Language
Here are some of the most common applications of Java Programming Language:
Mobile Applications
Java is recognized as the official programming language for creating mobile applications. It works well with tools like Android Studio and Kotlin. You might be curious about why Java is the preferred choice.
It operates on Java Virtual Machine (JVM), while Android utilises Dalvik Virtual Machine (DVK) for running class files. These files are then packaged as an Android application package (APK). Java and its Object-Oriented Programming (OOP) principles offer improved security and simplicity for Android.
Desktop GUI Applications
Java makes it simple to create desktop applications. It also lets you build graphical user interfaces (GUIs) using tools like Abstract Windowing Toolkit (AWT), Swing, and JavaFX.
AWT has ready-made components such as menus, lists, and buttons. Swing, on the other hand, is a toolkit for GUI widgets and includes more advanced elements like trees, scroll panes, tables, tabbed panels, and lists.
Web-based Applications
Java is employed for creating web applications as well. It offers extensive support for web applications using Servlets, Struts, or JSPs. Utilising these technologies, you can build various types of web applications as needed. The straightforward coding and strong security features of Java enable the development of numerous applications in areas like health, social security, education, and insurance.
Enterprise Applications
Many software developers prefer Java as their primary choice for writing applications, and Java Enterprise Edition (Java EE) stands out as a widely used platform. It offers an API and a runtime environment for scripting, covering network applications and web services.
Java EE is recognized as the foundation for numerous banking applications, where Java operates on the user interface (UI) and supports the server end.
Scientific Applications
Java is the preferred tool for software developers tackling scientific calculations and mathematical operations. These programs aim to be both highly secure and exceptionally fast. They boast enhanced portability and require low maintenance.
Java is utilised in influential applications such as MATLAB, where it serves both the user interface interaction and plays a role in the core system.
Application of Java Language in Real Life
Java has various applications in real life. However, here are some of the most common applications of Java language in real life:

Hence, having a grasp of the basics of the Java programming language is necessary for Android platform programming. Java Micro Edition (JME) is a common cross-platform framework for crafting Android apps. The Java compiler compiles Java classes into bytecode, which the Dalvik Virtual Machine uses.
Server Apps in Finance
For more than two decades, financial institutions and banks have extensively utilised Java for software development. Java has transformed the approach to collecting and organising data, providing a reliable platform for developing web applications in the FinTech industry. This object-oriented programming language is crucial in the Big Data ecosystem.
Given the substantial volume of data handled by finance companies daily, Java proves adept at managing such vast amounts securely. Within the finance sector, businesses and organisations utilise Java to build systems for settlement and confirmation, digital solutions, trading platforms, data processing systems, and various other applications.
Embedded Systems
Although widely known for other uses, Java was originally intended for constructing embedded systems, which are a blend of several small systems collaborating to perform a specific function. Java, recognized for its efficiency and the ability to handle exceptions seamlessly, is well-suited for this purpose. The Internet of Things (IoT), involving numerous interconnected devices, holds the promise of transforming our world by introducing new uses and business opportunities.

One of the rising applications of Java programming is Stock trading platforms. These platforms offer an uncomplicated way for stock traders to buy and sell commodities on several exchanges. Trading software requires to be extremely safe and scalable, as any lag could cause huge losses. It is assessed that more than 80 percent of electronic trading applications are written in Java.
The reason that this phenomenon has emerged is that the Java platform delivers the finest balance between execution, swiftness of application development, and ease of deployment and flexibility. Amongst the most noteworthy examples is the fact that almost all of the FIX engines are written in Java.
Best Uses of Java
Java fluency is undoubtedly a popular and in-demand skill. But what is the purpose of Java programming? We’ve previously touched on some Java use cases; we’ve elaborated on these and other Java examples further below.
Java can be used for many things:
Video games
When it comes to game development, programming languages such as C# and C++ are employed by game engines such as Unity and Unreal Engine. Java, on the other hand, is a great choice if you want to study graphics and game development from the ground up. There are numerous frameworks and libraries available, such as LibGDX and OpenGL.
Web-based programmes
Java is a well-known server-side programming language that is often used for constructing web applications. Spring, Struts, Hibernate, Apache Hadoop, and JSF are among the most popular Java frameworks for constructing Web applications. Java is also used by famous websites such as LinkedIn, AliExpress, Amazon, and many others.
Big data
Aside from Python, which is used in Big Data, there are many other popular programming languages. Even so, when it comes to Big Data Technology, most programmers prefer Java. The reason for this is that most famous Big Data tools, such as Hadoop and Deeplearning4j, use Java and its community support is excellent when it comes to Big Data Technology.
4 Types of Java Applications
- Standalone Applications
A program is run by a separate computer process without adding an existing file process is known as a standalone application. And also it does not require operating systems processes. AWT (Abstract Window Toolkit) and swing are used to create stand-alone applications.
- Web Applications
Web application is a client server software application which is run by the client. Web applications include mail, online retail sales, and Wikipedia. Servlet, jsp, jsf which are used to create web applications.
