To set up the JDK environment variable, you need to follow these steps:

  1. Download JDK: First, you need to download the JDK installation file from the official Oracle website or other reputable sources. Make sure to choose the version that is compatible with your operating system.
  2. Install JDK by running the installation program and following the instructions. During the installation process, you can choose to install JRE (Java Runtime Environment), which is necessary for running Java programs.
  3. To set the JAVA_HOME variable, right-click on “Computer” (or “This PC”) in the start menu, select “Properties.” Click on “Advanced system settings” (or “System” -> “Advanced system settings”) to open the system properties window. Under the “Advanced” tab of the window, click on the “Environment Variables” button. In the Environment Variables window, click on the “New” button. Set the variable name as “JAVA_HOME” and the variable value as the installation path of the JDK, for example: C:\Program Files\Java\jdk1.8.0_201.
  4. To set the Path variable: In the Environment Variables window, locate the Path variable and click the “Edit” button. In the editing window, click the “New” button, then enter “%JAVA_HOME%\bin”. This will add the JDK’s bin directory to the system’s executable path.
  5. To verify the installation, open the command prompt (or terminal window) and type in the command “java -version”. If the JDK has been successfully installed and the environment variables have been set up correctly, the Java version information will be displayed.

After completing the above steps, you have successfully set up the JDK environment variables. Now you can develop and run Java programs in the system.
