Let us look at the overview of Java and its features; and what certifications are best for learning Java.

What is Java?

Released in 1995 by Sun Microsystems, Java is a cross-platform, class-based, object-oriented programming language. Different applications such as games, social media applications, video and audio applications, etc

Java is free to access and can run on all the platforms. It is an independent programming language which means that you don’t need to write the code again and again for executing it on different machines. In other words, you can “Write Once, Run Anywhere” and the compiled code can be executed on all the platforms that support Java.

So, Java is a computing platform that can be used for developing applications.

A Java Developer is a professional responsible for writing powerful Java codes to design and build applications along with integrating the front-end to the back-end.

Features of Java

major features of Java programming

Simple and Easy

The complexities in C and C++ are removed and Java is made simple and easy to learn. This is the reason why most professionals prefer Java for full-stack development.

Object-oriented Programming Language

Since everything is considered to be an object, all the operations are carried out on these objects. Moreover, it eliminates the need of writing the same code again.


The dynamic memory allocation feature of Java makes it adaptable to evolving environments thereby reducing memory wastage and enhancing performance.


The strong memory management system of Java enables you to eliminate errors by checking the code during compilation and runtime.


Java allows you to create distributed applications by making use of RMI or Remote Method Invocation.


After compilation, all the code is converted into bytecode which is not readable by humans. It lets you build applications that are tamper-free and virus-free.


Java has JIT or Just-in-Time compilers which enhances the performance of applications.

Great Libraries and APIs

There are numerous open-source libraries in Java to help you solve complex problems quickly. It lets you create APIs or Application Programming Interface which makes interaction easy and quick.

By now, you have understood how versatile this programming language is. Let us now look at some of the best certifications you can go with, for making a career in full-stack development.
