This year, 2020, marks the 25th anniversary of the Java programming language. One of the most widely used programming languages, Java is used as the server-side language for most back-end development projects, including those involving big data and Android development.

Java is also commonly used for desktop computing, other mobile computing, games, and numerical computing. The popularity of Java is further evidenced with 90% of all Fortune 500 companies using Java.

So how popular is Java? Very.

The TIOBE Programming Community publishes an index showing the popularity of programming languages. The index is updated several times per year. The top ten programming languages, per the latest report, are shown below.

Note that Java has consistently held the number-one slot in the index since 2004!

Why Do Software Developers Use Java?

The portability of Java contributes to its wide use and popularity, but there are other reasons why software developers continue to choose Java.

Since it is an object-oriented language; it’s robust, secure and relatively simpler and easier to learn than languages such as C and C++.

Object-oriented languages make complex problems easier to solve and provide greater modularity. This is a natural and pragmatic approach for software design. Java objects encapsulate data and behavior so that code can be reused, which makes testing and troubleshooting easier.

With Java, objects are created using classes that define the attributes (data) and behaviors (defined by methods coded in the class). Java features such as inheritance further contribute to simplified code. With inheritance, similar but different types of objects are simplified by inheriting common attributes and behaviors from the parent class. This allows reuse of the common code while allowing for differences.
