How To Install Java JDK 1.8 On Windows

Here’s a concise step-by-step guide for installing Java JDK 1.8 on Windows:

1. Download JDK 1.8 Installer

• Visit Oracle’s website: Navigate to the Java SE 8 Downloads page.
• Accept License Agreement: Check the “Accept License Agreement” box.
• Download Windows installer: Select the appropriate version (e.g., jdk-8uXXX-windows-x64.exe for 64-bit systems).
  Note: An Oracle account may be required to download older versions like JDK 1.869.

2. Run the Installer

• Double-click the downloaded .exe (e.g., jdk-8uXXX-windows-x64.exe).
• Follow the setup wizard:
  • Click Next on the welcome screen.
  • Customize installation path (optional): Use the Change button to set a custom directory (e.g., C:\Java\jdk1.8.0_XXX)69.
  • Complete the installation and close the wizard.

3. Set Environment Variables

JAVA_HOME Variable

1. Open System Properties → Advanced → Environment Variables.
2. Under System variables, click New.
   • Variable name: JAVA_HOME
   • Variable value: Installation path (e.g., C:\Program Files\Java\jdk1.8.0_XXX)59.

Update PATH Variable

1. In System variables, select Path → Edit.
2. Click New and add:
   %JAVA_HOME%\bin
   (This allows Java commands to run globally)57.

4. Verify Installation

• Open Command Prompt and run: bashjava -version javac -version
  • Expected output:
    java version "1.8.0_XXX"
javac 1.8.0_XXX5710.

Troubleshooting

• “Java not recognized”: Recheck PATH and JAVA_HOME values7.
• Installation conflicts: Uninstall older Java versions via Control Panel before installing JDK 1.810.
• Silent installation: For enterprise setups, use the MSI installer with msiexec.exe /i jdk-8uXXX.msi /qn19.

Optional: Install JRE

The JDK installer typically includes a JRE. If missing, download it separately from Oracle’s site9.
