What are the main features of Java?

Java Basics

Java's core features include platform independence, object orientation, automatic memory management, multithreading support, robustness (strong compile-time and runtime checking), and security through the JVM sandbox and bytecode verification.

Core Features

• Simple: no explicit pointers, no operator overloading • Object-Oriented: everything (except primitives) is modeled as objects • Platform Independent: bytecode runs on any JVM • Secure: bytecode verifier + classloader + security manager • Robust: strong type checking, exception handling, garbage collection • Multithreaded: built-in support for concurrent programming • High Performance: JIT compiler translates hot bytecode to native code

Interview Answer

I'd highlight platform independence via the JVM, automatic garbage collection removing manual memory management, strong compile-time type checking, and built-in multithreading — these are what make Java a reliable choice for large, long-lived enterprise systems.
