Features of Java:
Simple:
Java is easy to learn compared to C++.
No pointers
No complex memory handling
Clean and readable syntax
Meaning:
Java is simple because it removes complex programming features and keeps code easy to understand.
Object-Oriented:
Java is fully based on OOP concept.
Everything is written using:
Class
Object
OOP principles:
Encapsulation
Inheritance
Polymorphism
Abstraction
Meaning:
Java organizes code using objects, making it reusable and structured.
Platform Independent
Java works on any operating system.
Reason:
Java code is converted into bytecode and runs on JVM.
Meaning:
Write once, run anywhere (Windows, Linux, Mac)
Secure
Java is very secure.
No direct memory access
Runs inside JVM sandbox
Bytecode verification
Meaning:
Java prevents hacking and unsafe memory access.
Robust
Java is strong and reliable.
Automatic memory management (Garbage Collector)
Exception handling
No pointer issues
Meaning:
Java programs are stable and rarely crash.
High Performance:
Java is faster due to JIT compiler.
Converts bytecode to machine code during execution
Optimizes performance
Meaning:
Java runs fast for large applications.
Multithreaded
Java supports multiple tasks at the same time.
Example:
Music playing
File downloading
Meaning:
Java can handle multiple tasks simultaneously.
Portable
Java code can run on any system without modification.
Reason:
Same bytecode works everywhere with JVM.
Meaning:
Java programs are easily transferable across systems.
