Second, add two variables and change a variable:

1, variable name: java_home

Variable value: Where Java files are located

2, variable name: CLASSPATH

Variable value:.; %java_home%\lib\dt.jar;%java_home%\lib\tools.jar;

3. Change the variable contents of path.

Variable name: Path

Variable value:%java_home%\bin;%java_home%\jre\bin is added before the value of its original variable; The original variable value is too long, you can press the home key to find the value of the front of the variable.
