1. Download the Java Development Kit (JDK) installer: Go to the official Oracle website or the AdoptOpenJDK website to download the JDK installer. As of my last update in September 2021, I recommend using AdoptOpenJDK as it provides open-source JDK distributions.

Here’s the link to AdoptOpenJDK: https://adoptopenjdk.net/

2. Choose the appropriate JDK version: Depending on your requirements, choose either the latest stable version or a specific version of the JDK.
3. Run the installer: Locate the downloaded JDK installer executable (.exe) file and double-click on it to run the installation wizard.
4. Follow the installation wizard: The installation wizard will guide you through the installation process. You may be asked to accept the license agreement, choose the installation directory, and configure additional options.
5. Set environment variables (optional): In some cases, the installer will set the necessary environment variables for you. However, if they are not set automatically, you might need to do it manually. These variables include:
   • JAVA_HOME: Points to the JDK installation directory.
   • PATH: Includes the JDK bin directory in its value.
6. Verify the installation: After the installation is complete, open a Command Prompt or PowerShell window and type the following command to verify that Java is installed correctly:

Copy code

java -version

If Java is installed correctly, you will see the installed version and other relevant information.

That’s it! Java should now be installed on your Windows system, and you can start developing and running Java applications.
