What is Java Programming Used for?

First Glimpse

Software engineers are not just application programmers; they are supposed to build and structure products for clients that meet their expectations, provide the features they need and be supported by a strong backup. Java is one smart solution to lay the foundation for such robust utilities, and it allows developers to be efficient, effective and innovative – without having to reinvent the wheel.

Java always seems to come out on top; it’s a well-loved and popularly implemented language and there’s a whole host of reasons why.

Java has gained enormous popularity since it first appeared in 1995. Its rapid popularity and wide acceptance are explained by its design and programming features, particularly in its promise that you can write a program once, and run it anywhere. Java was chosen as the programming language for network computers and has been perceived as a universal front end for the enterprise database.

As stated in Java language white paper by Sun Microsystems: “Java is a simple, object-oriented, distributed, interpreted, robust, secure, architecture neutral, portable, multithreaded, and dynamic.” By having foundations in readability and simplicity, Java is the programming language of choice for creating long-term compatibility since it ensures older applications to continue working into the foreseeable future.

According to Tech Target, the essentials of Java:

‘Java is a programming language expressly designed for use in the distributed environment of the Internet. It was designed to have the “look and feel” of the C++ programming language, but it is simpler to use than C++ and enforces an object-oriented programming model.’

Why Is Java so Popular?

Java is one of the most trendy programming languages. But what is the reason for that?

The TIOBE index called Java the most popular language in July 2018. According to TIOBE Programming Community, this index is used to check whether your programming skills are still up to date or to make a strategic decision about what programming language should be adopted when starting to build a new software system.

The answer lies primarily with the exhaustive testing, updating and consistency of delivery that Java has historically provided. Java has been tested, refined, extended, and proven by a dedicated community of Java developers, architects and enthusiasts. Despite origins dating back almost two decades, it has consistently evolved over the years.

Java is designed to enable development of portable, high-performance applications for the widest range of computing platforms possible, hence enabling the fundamental tenets of overarching accessibility as well as cross-platform interaction. By making applications available across heterogeneous environments, businesses can provide more services and boost end-user productivity, communication, and collaboration—and dramatically reduce the cost of ownership of both enterprise and consumer applications.

Developers all around the globe most of all love Java. For many of them, programming languages begin and end with Java. This language is used to create customized software products, web portals and web applications, including eCommerce and m-Commerce solutions.

With the developing significance of web-based and mobile based applications, Java today is playing the key role in implementing most arranged applications and is regarded as applicable for enterprise software, web-based content, scripting, games and mobile applications.

Without any doubt Java takes the lead in software development, it would be wrong to underestimate other programming languages. So the true expert it is really crucial monitor trends and tendencies of IT sphere, to know which programming language will suit the particular software project.

History of Java Programming

Java is a high-level programming language and computing platform developed by Sun Microsystems in 1994. Its history starts with Green Team. Java team members founded it to develop a language for digital devices such as set-top boxes, televisions, etc. Yet, it corresponded to the internet programming. Afterwards, Java technology was included to Netscape.

The basic tenets of Java programming included: “Simple, Robust, Portable, Platform-independent, Secured, High Performance, Multithreaded, Architecture Neutral, Object-Oriented, Interpreted and Dynamic”.

Now, Java is implemented in internet programming, games, e-business solutions, mobile devices, etc. Java language has been regularly updated with Java SE 11 version being the latest version.

The Usage of Java

Every enterprise uses Java in one way or another. As per Oracle, more than 3 billion devices run applications designed on the development platform. Java is used to design the following applications:

  • Desktop GUI applications
  • Web servers and application servers
  • Embedded systems
  • Enterprise applications
  • Middleware products
  • Web applications, including e-Commerce applications, front and back office electronic trading systems, settlement and confirmation systems, data processing projects, and more
  • Mobile applications including Android applications
  • Scientific applications

In light of the Java’s benefits, it increased wide fame and different arrangements have been worked to suit different sorts of stages including Java SE for Macintosh, Windows and UNIX, Java ME for Mobile Applications and Java EE for Enterprise Applications.

Based on the advantages of Java, it has received wide popularity and multiple configurations have been built to fit different types of platforms including Java SE for Macintosh, Windows and UNIX, Java ME for Mobile Applications and Java EE for Enterprise Applications.

Advantages of Java

  • Easy to learn: Java was designed to be easy to use, write, compile, debug, and learn than other programming languages. Java is much simpler than C++ because Java uses automatic memory allocation and garbage collection.
  • Distributed: With each release, the community of developers who contribute to Java development come up with highly advanced and sophisticated APIs and libraries, These are available as ready-to-use packages to build reliable and strong network systems
  • Platform-Independent: Unlike C and C++, Java programs are compiled independently of the platform in bytecode language which allows the same program to run on any machine that has a JVM installed.
  • Object-Oriented: Allows you to create modular programs and reusable code.
  • Multithreaded: The capability for a program to perform several tasks simultaneously within a program. It is useful in multimedia and other real-time applications.
  • Allocation or Self-Memory Management: The coder does not have to be concerned about the memory logistics, allocation and de-allocation of objects. JVM will take care about it.
  • Secure: Upon compilation, source code written in Java gets compiled into bytecode, which is later interpreted by the Java Virtual Machine. Bytecode is resistant to tampering by external agents.
  • Being highly popular at an enterprise, embedded and network level, Java has a large active user community and support available.
  • Increasing language diversity, evidenced by compatibility of Java with Scala, Groovy, JRuby, and Clojure
  • High Performance: JIT compilation provides both high speed and high performance.


In conclusion, even after 23 years after its inception, Java continues to evolve and deliver considerable value to the world of software development. It has become a programming language for providing worldwide Internet solutions. Java offers new features such as a scalable and flexible platform for the Internet of Things, less boilerplate code, new date and time library and API, refreshed graphics toolkit, integration with JavaScript, and others.
