Features of Java – Learn Why Java Is Important

Today, 9 million+ developers are using Java. In fact, Java is the most popular and widely used programming language on earth. Did you ever think, what is the secret behind its popularity? It’s Features. The Features of Java is the main reason behind it being the “King of All Programming Languages”. If we talk about the TIOBE index, we discovered that Java is holding the 1st position for the last 3 years.

Features of Java empowers secure, easier and faster work for every developer. Currently, we are seeing a tough battle between Python and Java. By the end of this article, you will get to know why Java is trending and why developers choose Java over Python.

So its time to tighten your seat belts and get ready to learn the various features of java.

Features of Java

Speaking about its features, let’s find out what makes java worth learning. The primary reason behind the creation of Java Programming was to make it portable, simple and secure language. Apart from this, there are some excellent features which play an important role in the popularity of this language.

List of features of Java programming language-

1. Simple

Java is designed in such a way that it could be learned easily. If you understand the basic concepts of Object-Oriented Programming, then it would be easy for you to master Java. It is a simple language as it is derived from C and C++. In Java, there is also a facility for automatic garbage collection so that you don’t have to delete unreferenced objects manually.

2. Object-Oriented

Java is an Object-oriented language, everything in Java is an object as it modeled around ‘objects’ rather than the ‘process’. Object-oriented programming has the following concepts-

  • Object
  • Class
  • Inheritance
  • Polymorphism
  • Abstraction
  • Encapsulation

3. Platform Independent

Java is platform-independent because it is independent of whatever software environment is available.

java platform independent

The java source code can run on multiple operating systems. Java code runs on any machine that doesn’t need any special software to be installed, but the JVM needs to be present in the machine.

It has two components

  • Runtime Environment
  • API (Application Programming Interface)

Java code is compiled into bytecode, which is platform-independent. You can run it on Windows, Linux, Mac OS, etc. It runs on multiple platforms as the program written is compiled and then the bytecodes generated is platform-independent code, Java offers the feature “Write Once, Run Anywhere (WORA)”.

4. Secure

Java is a secure language because it has the following features –

  • Java has no explicit pointer.
  • Programs run in a virtual machine sandbox.
  • Java adds a class loader that separates the classes for a package of the local file system from imported ones from a network.
  • It has a bytecode verifier that checks the code fragments for any illegal code that violates the access right.
  • It has a security manager that defines the access of Java classes.

5. Robust

Java is a robust language as it uses strong memory management and lack of pointers helps in improving security issues. Automatic garbage collection, exception handling, and type checking mechanism features make it a very strong language.

6. Neutral Java Architecture

In Java, the code is compiled and thus bytecode is generated. These bytecodes can run on any computer architecture thus it makes Java architecture-neutral.

7. Portable

Java is a highly portable language as the bytecodes can be carried to any platforms. Java code can be executed on all the major platforms. Once you’ve compiled your Java source code to bytecode, those files can be used on any Java-supported platform without modification, unlike other languages, which requires compiling the machine code for each platform, for example, a separate .exe for 32-bit vs 64-bit environments.

8. Distributed Applications

Java can create distributed applications using RMI and EJB. This feature of Java facilitates the user to call any file by calling any method on any computer.

9. Multi-Threading

A thread is a different program that runs concurrently, this feature helps Java to handle multiple tasks simultaneously. Threads don’t occupy memory, they work on memory sharing. If we want to execute multiple programs simultaneously, then we use multithreaded architecture.

10. Dynamics

Java is a dynamic language which means it can link new Java class libraries, Java objects, and Java methods dynamically. It also supports functions from its native languages such as C and C++.


The above-discussed features of Java are going to help you in a number of ways in your programming journey. Here you got to know the importance of Java and also discovered its efficiency.

Through this article, you must be clear why java is so popular among programmers. This proves that learning Java is worth.

    The features of Java, explained in this Features of Java tutorial are complete in itself. To add more to why Java is Important, Java’s platform independence, portability and security are the primary reasons of it’s popularity. Platform independence and portability are often confused to be the same but they both are different. Portable refers to transferring from one platform to another whereas platform independence refers to the application which can run on any operating system. This was something I had to Say on Features of Java.
