Java Introduction

Java is a versatile, platform-independent, and widely used object-oriented programming language. Developed by James Gosling and released by Sun Microsystems in 1995, Java is now maintained by Oracle Corporation. It is designed to let developers write code that can run anywhere (the "write once, run anywhere" principle), thanks to its use of the Java Virtual Machine (JVM).

Key Features of Java

Object-Oriented: Java is built around the concept of objects and classes, making it modular, reusable, and easy to maintain.

Platform-Independent: Java programs are compiled into bytecode, which can be executed on any machine with a JVM, regardless of the underlying operating system.

Simple and Familiar: Java syntax is simple and easy to learn, especially for those familiar with C or C++.

Robust: Java emphasizes error checking at runtime and compile time, reducing the likelihood of bugs.

Secure: Java provides built-in security features such as bytecode verification, a robust exception handling mechanism, and a security manager.

Multithreaded: Java supports concurrent programming, enabling applications to perform multiple tasks simultaneously.

Distributed: Java's built-in APIs like RMI and CORBA allow programs to run in distributed environments.

High Performance: While not as fast as C or C++, Java's Just-In-Time (JIT) compiler helps improve performance significantly.

Dynamic: Java supports dynamic loading of classes and runtime reflection, making it highly adaptable.

Example
public class Main {
public static void main(String[] args) {
System.out.println("Hello, World!"); // Print message to console
}
}

Try it yourself

Explanation:

  1. public class Main: Defines a class named Main.
  2. public static void main(String[] args): The entry point of the Java application.
  3. System.out.println("Hello, World!");: Outputs the string "Hello, World!" to the console.
