Features of Java Programming

Security

Java is a safe language because there are no explicit pointers used and all the programs are run inside the sandbox to protect them from any untrusted sources. Java develops a virus-free system and converts all code into bytecodes that are not read easily readable by humans.

Portable

The key feature of Java is its portability because it can run on all operating systems without any dependency. Java is platform-free which means that any application written on one platform can be easily run to another platform.

Robust

Java’s robust memory management system helps to correct errors by checking codes during run time. Java programming is robust because it fully takes care of memory allocation and release.

Object-oriented

All tasks in Java are done using objects. Java is thus an object-oriented programming language. All these things have some behavior. Therefore, it is the most commonly used language because it supports the concepts of OOPs.

Therefore, the above are some of the important features or services that are provided to industry programmers by Java programming language vendors.
