What Can You Do with Java Programming Language?

Desktop Applications

One of the most popular uses of Java is developing client-side desktop applications, which requires the end user to install a Java runtime environment (JRE) on their system. The JRE is available for all major operating systems and is generally included as part of the default installation of most Linux distributions and some BSD variants.

Server-Side Web Applications

Another widespread use of Java is developing server-side web applications. Server-side web apps are Java applications that run on a web server and respond to requests from web clients, usually in the form of HTML pages.

Enterprise Applications

Java is the first programming language for enterprise app development. Enterprise applications are business applications that organizations use to conduct their day-to-day business. Many enterprise apps are written using a client-server architecture where the client is often an off-the-shelf software package running on desktop computers and connecting to that server via a thin layer of custom code or middleware.

Backend Processing

Many organizations use Java for backend processing, such as in their batch processing jobs. Backend processing involves performing some processing during off-peak hours to reduce users’ impact during regular working hours.

Android Applications

Android apps are written in Java programming language and run on an Android Virtual Machine (VM). These applications can either be pre-installed on a device or downloaded from Google Play Store.

Embedded Systems and Microcontrollers

Java is used for developing embedded systems which are special-purpose computer systems designed to perform one or some limited set of tasks and have minimal size, power consumption, and cost. Although they can be used for a wide variety of applications, many embedded devices are restricted by the physical size and power of their processors, memory, and other components.

Scientific and Mathematical Applications

Java is also famous for developing scientific and mathematical applications. Scientific applications are used to solve problems in science and mathematics, while mathematical applications are used to perform mathematical operations on data.

Desktop GUIs

Developing desktop graphical user interfaces (GUIs) is another use of Java utilized by end-users to interact with the system via visual feedback.

Cross-platform Applications

Java is prevalent for developing cross-platform applications that can be run on different operating systems like Windows, Linux, and MacOSX or different processor architectures like ARM and x86.

Mobile Applications

Mobile apps are software applications built to run on smartphones and tablet computers. With this programming language, a Java programmer can create complete applications. Many mobile apps are written using the Java programming language and run on a Java Virtual Machine (VM).

Real-time Systems

Software developers can build real-time systems with Java. Real-time systems are computer systems that need to respond to events in a timely manner. They are used in a variety of applications, including manufacturing, aerospace engineering, military, and transportation. Java is popular for developing real-time systems because it has features that make it suitable for this type of application, such as its deterministic garbage collector and runtime system.
