To set up the Java JDK environment variable, you can follow the steps below:

  1. Download and install Java JDK. You can download the Java JDK installation package for your operating system from the official Oracle website. Remember the installation path during the installation process.
  2. Open the environment variable settings of the system. On a Windows system, you can press the Win + R keys, then enter “sysdm.cpl” to open the “System Properties” window. Under the “Advanced” tab, click on the “Environment Variables” button.
  3. Click on the “New” button in the “System Variables” section.
  4. Set the variable name as “JAVA_HOME” and its value as the path where your Java JDK is installed. For example, if you have installed Java JDK in the directory “C:\Program Files\Java\jdk1.8.0_231”, then the variable value should be “C:\Program Files\Java\jdk1.8.0_231”.
  5. In the “System Variables” section, locate the variable named “Path” and click on the “Edit” button.
  6. In the “Edit Environment Variables” window, add “;%JAVA_HOME%\bin” at the end of the “Variable Value” input box. Please note that different systems may use different separators, such as Windows using a semicolon “;” and Linux using a colon “:”.
  7. Click “OK” to save the settings and close all windows.
  8. Open the command prompt or terminal window, type the command “java -version”. If it correctly displays the Java version information, then the environment variable is set up successfully.

Please note that the above steps are only applicable to Windows systems, and there may be some differences for other operating systems.
