3. Set two places in total, the first one, configure JAVA_HOME, click "New"

4. Enter JAVA_HOME for the variable name, and select the path when you install JDK for the variable value. The default path is C:\Program Files\Java

5. The second is to configure the path variable, just enter %JAVA_HOME%\bin

Why does the above need to create a new JAVA_HOME?
Because if you need to use other JDK versions in the future, the installation directory needs to be changed at any time, so create a new fixed variable JAVA_HOME in the path, and you only need to change the path of JAVA_HOME in the future, and the path does not need to be changed.
