Java Setup and Installation

Setting Up Java

To start coding in Java, install the JDK (Java Development Kit) and a code editor like VS Code, IntelliJ IDEA or even an online compiler.

Installation Steps (Windows)

Download the JDK from Oracle's website (or use OpenJDK, which is free).
Run the installer and finish setup.
Set the PATH environment variable to the JDK's bin folder.
Verify in Command Prompt:

java -version
javac -version

java version "17.0.x" javac 17.0.x

Quick Start (No Install)

Beginners can skip installation and use a free online compiler (like the ones on programiz or replit) to run Java directly in a browser.

Summary

Install the JDK and a code editor (or use an online compiler).
Set PATH to the JDK bin folder.
Verify with java -version and javac -version.
