How can I set environment variables for Java in Windows?

To set environment variables for Java on a Windows system, follow these steps:

1. Open System Properties

• Press Win + Pause/Break to open System Properties.
• Alternatively, right-click This PC or My Computer, select Properties, and click Advanced system settings.

2. Navigate to Environment Variables

• In the System Properties window, go to the Advanced tab.
• Click on the Environment Variables button.

3. Set the JAVA_HOME Variable

• Under System variables, click New.
• In the Variable Name field, enter JAVA_HOME.
• In the Variable Value field, enter the path to your Java installation directory (e.g., C:\Program Files\Java\jdk-XX.X.X).

4. Add Java to the Path Variable

• In the System variables section, find and select the Path variable, then click Edit.
• Click New and add %JAVA_HOME%\bin.
• Ensure that it is added as a separate entry for proper recognition.

5. Save and Apply Changes

6. Verify the Configuration

• Open a Command Prompt (Win + R, then type cmd and hit Enter).
• Type java -version to verify that Java is correctly installed and the path is set.
• You can also type echo %JAVA_HOME% to check the value of the JAVA_HOME variable.

Notes:

• Ensure the correct version of the JDK is installed.
• If you encounter issues, check for typos or incorrect paths.
• Restart your Command Prompt or IDE to ensure it recognizes the updated environment variables.
