1. Simple: Easy-to-read syntax, similar to C/C++ but without complex features like pointers or operator overloading.
2. Platform Independent: Java code compiles to bytecode which runs on any system with a JVM – enabling Write Once, Run Anywhere (WORA).
3. Object-Oriented: Supports core OOP principles – Encapsulation, Inheritance, Polymorphism, Abstraction – using classes and objects.
4. Secure: Provides built-in security via bytecode verification, access control, exception handling, and sandboxing.
5. Robust: Strong error handling with automatic garbage collection, exception handling, and runtime checks.
6. Multithreaded: Supports concurrent execution of multiple threads for efficient CPU usage and performance.
7. High Performance: The JIT compiler converts bytecode to native code at runtime for faster execution.
8. Distributed: Supports distributed computing using RMI, CORBA, and Web Services.
9. Dynamic: Supports runtime class loading and reflection, making programs flexible and adaptive.
10. Rich API: Comes with extensive libraries for data structures, I/O, networking, GUI, and more.
