This guide will walk you through the steps to install the JDK on your Windows 11 PC, enabling you to start developing Java applications in no time.
Step 1: Download the JDK Installer
Visit the Oracle website to download the JDK installer.
Navigate to the Java SE Development Kit downloads page. Ensure you’re downloading the version compatible with Windows 11. Choose the .exe file for an easier installation process.
Step 2: Run the Installer
Locate the downloaded .exe file and double-click it to start the installation process.

Step 4: Set Up System Environment Variables
Open the System Properties dialog by right-clicking on ‘This PC’ and selecting ‘Properties’.
Click on ‘Advanced system settings’, then ‘Environment Variables’. Under System Variables, find the ‘Path’ variable, then click ‘Edit’. Add the path to the JDK bin directory, typically something like C:Program FilesJavajdk-bin.
Step 5: Verify the Installation
Open Command Prompt and type java -version and javac -version to verify the JDK installation.
If everything is set up correctly, you should see the JDK version details. This confirms that your system recognizes the JDK.
After completing these steps, your Windows 11 machine is ready to compile and run Java programs. You can now start developing with Java, using your favorite IDE or text editor.
