Features of Java – Learn Why Java Is Important
The reason behind inventing java is to bring the security feature in the programming languages which is one of the best reasons that 9 million developers are using java. Java Features are responsible for making it popular in the IT industry.
As of now, we are well established with the fact of Java programming and having a proper introduction to Java. Now it’s time to discover the various salient features of java.
Its a bet that after reading these you will feel like that your java skills are upgraded.
We will also aware of you the fact, that why these features are important. Various features of Java will help you to understand why Java is important and help you to learn java in a very effective and efficient manner.
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-
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.
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-
3. Platform Independent
Java is platform independent because it is independent of whatever software environment is available.
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)”.
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 ofJava classes.
Java is a robust language as it uses strong memory management and lack of pointers helps in improving security issues. Automatic garbage collection and exception handling and also type checking mechanism all 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.
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.
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.
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 to be that learning Java is worth it.
