Step 2: Run the Downloaded JRE
- Once the download is complete, run the downloaded JRE (Java Runtime Environment) file.
- Follow the on-screen instructions to install the JRE.
Step 3: Add JDK to System Environment Variables
- After installing the JRE, you need to add it to your system environment variables.

Step 4: Set Java Home Variable
- To ensure that the JDK is used as the default Java installation, you need to set the Java home variable.
- To do this, follow these steps:
- Right-click on Computer or This PC and select Properties.
- Click on Advanced system settings on the left side.
- Click on Environment Variables.
- Under System Variables, scroll down and find the Java Home variable, then click Edit.

C:Program FilesJavajdk-8.0.1). - Click OK to close all the windows.
Step 5: Verify JDK Installation
- To verify that the JDK is installed correctly, you can use the following command:
java -version(for Java 8) orjava -version(for Java 11 or Java 17)- This should display the version of the JDK installed on your machine.
Troubleshooting Tips
- If you encounter any issues during the installation process, you can try the following troubleshooting steps:
- Check the JDK installation directory to ensure that it is correct.
- Verify that the JDK is installed in the correct location (e.g.,
