After hearing about the huge career potential of Java or the great salary, several students are moving towards¬†Java training. But, most of them are still not aware of the capabilities of Java. They don’t know what does Java do exactly. So, in this blog, we will discuss what Java is, its features, and what does Java do.

What Is Java?

Java is a high-level, general-purpose, object-oriented, and class-based programming language. James Gosling developed Java at Sun Microsystems. It was officially released in 1995 as a core element of Sun Microsystems’ Java platform. Java language is designed with only a few implementation dependencies. 

As Java is a general-purpose programming language, it is used for several different purposes. We’ll discuss what does Java do later in this blog. Java language programs are first converted to bytecode that can be executed on any machine having Java Virtual Machine(JVM). Due to this bytecode functionality, Java follows the concept of WORA(Write once, run anywhere). Also, the syntax of Java is somewhat similar to C/C++, but Java does not support many low-level facilities. 

Also, Java is an object-oriented programming language, it supports all the important OOPs concepts, such as inheritance, abstraction, polymorphism, and encapsulation.

Features Of Java Programming

Before discussing what does Java do, students should know the important features of Java. Following is the list of various important features of Java programming:


Java is a very easy to use and learn programming language. The syntax of Java is clean and straightforward. Java does not support the complex features of other popular languages such as pointers, storage classes, operator overloading, etc.

Platform Independent

Java follows the concept of WORA(Write Once, Run Anywhere), which makes it a platform-independent programming language. Java source code is first converted to BYTE code(intermediate code) which is then converted to the machine-level code by JVM(Java Virtual Machine). We can write code on any computer system and run it on another computer system using JVM without worrying about the different computer architecture.


Java is a pure object-oriented programming language. It supports all the important object-oriented programming features, such as encapsulation, polymorphism, abstraction, and inheritance. Almost every element in Java is treated as an object, and all the data and programs reside within objects and classes.


Java supports exception handling and automatic garbage collection to handle runtime errors, making it a robust language. Also, the memory management system of Java is very strong.


Java is a very secure language and can develop virus-free systems. It has a classloader, bytecode verifier, a virtual machine sandbox, a security manager, and no explicit pointer.

What Does Java Do?

Here is the list of things that will give you the answer to what does Java do:

Things Java can do

Mobile App Development

Java is the primary language for developing Android mobile applications. Java is used in the development of most android applications. Android Studio is the most popular IDE(Integrated development environment) to develop android applications. Some of the most popular mobile applications made with Java are Netflix, Google Earth, Twitter, Uber, etc.

Game Development

Game development is another thing that Java can do. Java supports the open-source most powerful 3D engine. Some of the most loved games of today’s generation are built using Java programmings, such as  Saints Row 2, Spiral Knights, Minecraft, Asphalt 6, and RuneScape. Java also supports jMonkeyEngine and Dalvik Virtual Machine to develop 2D and 3D android mobile games.

Cloud Applications

What Does Java Do? Cloud applications can be one of the best things that Java can do. Cloud computing is simply the on-demand access to computing resources such as storage, servers, databases, software, networking, etc. Developers can use Java programming to develop LaaS (Logging as a Service), PaaS (Platform as a Service), and SaaS (Software as a Service). Cloud applications help companies to develop applications remotely or for data sharing.

Web Applications

Java can be used to create high-quality web-based applications. Java provides secure and simple coding that attracts web application developers to it. Java supports JSPs, Struts, and Servlets that has the potential to develop any kind of web application. Spotify, Netflix, LinkedIn, Amazon, and Uber are popular web-based applications built with Java programming.

Scientific Applications

Java language is one of the best choices for developing scientific applications. Java is an extremely fast, portable, and secure programming language that satisfies all the scientific application requirements. MATLAB is the best example of a scientific application created using Java. MATLAB  uses Java in its back-end as well as front-end.

Java Distributed Applications

Distributed applications are another good answer to what does Java do. Distributed applications are those applications that run on multiple computers on the same network. 

Distributed applications can have multiple common requirements because of the dynamic servers quality, platform on which they operate and distributed characteristics.  CORBA (Common Object Request Broker Architecture) and RMI (Remote Procedure Invocation)are the popular Java APIs to originate distributed applications.

Jini or Java intelligent networking infrastructure is used to provide, find, and register distributed services on the basis of its specifications. JavaSpaces is an important component of Jini. It is a mechanism that supports object persistence, distribution, and migration in a distributed environment.

Desktop applications

Desktop applications are software programs designed to run on personal computers or laptops. Java provides a rich set of libraries and tools that enable developers to create desktop applications for various purposes, such as productivity, entertainment, or education. 

The advantages of developing Java desktop applications include Platform independence, a Rich user interface and security.

Enterprise applications

They are software programs designed to support large organizations’ operations, such as corporations, governments, and non-profits. Java is widely used for developing enterprise applications due to its robustness, scalability, and platform independence.
