• 1 Java code is compiled into bytecode.
• 2 Bytecode runs on JVM, not directly on OS.
• 3 Works on Windows, Linux, and macOS.
• 4 This is called Write Once, Run Anywhere (WORA).

• 1 Java is fully object-oriented (class-based).
• 2 Supports encapsulation, inheritance, polymorphism, abstraction.
• 3 Helps in code reusability and modular design.

• 1 Java runs inside a secure runtime environment.
• 2 No direct memory access like C/C++.
• 3 Bytecode verifier ensures safe execution.

• 1 Automatic garbage collection manages memory.
• 2 Strong type checking reduces errors.
• 3 Exception handling improves reliability.

• 1 Java supports multiple threads execution.
• 2 Improves performance of applications.
• 3 Useful for servers, games, and real-time apps.

• 1 Java provides built-in libraries for many tasks.
