Features of Java

Last updated: 28 Sep 2026

Java is popular because of a small set of core features:

• Simple: no pointers or operator overloading.
• Object-oriented: everything is organised in classes and objects.
• Platform independent: bytecode runs on any JVM.
• Secure: the JVM verifies code before running it.
• Robust: strong type checking, exception handling and automatic garbage collection.
• Multithreaded: built-in support for running tasks in parallel.
