Features of Java

Java is a high-level, platform-independent programming language used to develop secure and scalable applications.

Features of Java

1) Simple

Java is easy to learn and use because:

• Syntax is similar to C/C++

• Removes complex features like pointers and operator overloading

2) Object-Oriented

• Java follows OOP concepts, such as: Class & Object, Inheritance, Polymorphism, Encapsulation, Abstraction

• This helps in building reusable and modular code.

3) Platform Independent (WORA - Write Once Run Anywhere)

• Java code is compiled into bytecode

• Runs on any system using the JVM (Java Virtual Machine)

4) Secure

Java is highly secure because:

• No pointers (reduces memory access issues)

• Has a Security Manager

• Bytecode verification prevents unsafe code

5) Robust

Java is strong and reliable because:

• Automatic memory management (Garbage Collection)

• Exception handling

• Strong type checking

6) Multithreaded

Java supports multithreading, which means:

• Multiple tasks can run simultaneously

• Improves performance (used in apps, games, servers)

7) High Performance

• Uses Just-In-Time (JIT) compiler

• Faster than traditional interpreted languages

8) Distributed

Java supports distributed applications:

• Can work across networks

• Used in web services, APIs

9) Dynamic

• Classes can be loaded at runtime

• Supports dynamic memory allocation

10) Portable

• Java programs can run on any device without modification

• Only JVM is required

11) Architecture Neutral

• No dependency on hardware architecture

• Bytecode works on all processors

12) Interpreted + Compiled

Java is both:

• Compiled → into bytecode

• Interpreted → by JVM
