Complete Guide: Installing JDK 8 on Windows

JDK 8 remains one of the most popular and stable versions of Java used in the industry today. Whether you are a student or a professional developer, setting up your environment correctly is the crucial first step. This guide will walk you through the process in the simplest way possible.

Step 1: Download the JDK 8 Installer

Visit the official Oracle website and navigate to the Java SE 8 downloads section. You'll need to accept the license agreement and select the "Windows x64" version if you are on a 64-bit system. Once the download is finished, you're ready to start!

Step 2: Run the Setup Wizard

Double-click the downloaded .exe file. The installation wizard will guide you through the process. Most users can simply click "Next" through the prompts, keeping the default installation path, which is usually C:\Program Files\Java\jdk1.8.x.

Step 3: Setting Up Environment Variables

This is the most important part! To make Java work in your command line:

Go to System Properties and click on Environment Variables.
Create a new System Variable named JAVA_HOME and point it to your JDK folder.
Find the Path variable and add %JAVA_HOME%\bin to the list.

Step 4: Verify the Installation

Open a new Command Prompt window and type java -version and javac -version. If you see "1.8" in the results, congratulations! You have successfully installed Java on your Windows machine.
