- Download and install (omitted)
- Configure environment variables (admin/system)
Anyway, the method is the same. The path I installed is: D:\Java\jdk-12.0.1
To configure system variables, configure JAVA_HOME and Path in this part
JAVA_HOME ： D:\Java\jdk-12.0.1
Path: Add: %JAVA_HOME%\bin
To configure administrator variables, configure JAVA_HOME and Path in this part
JAVA_HOME ： D:\Java\jdk-12.0.1
Path: Add: %JAVA_HOME%\bin
Among them, the configuration location of these two variables is to create a new JAVA_HOME in the Administrator box and add it after Path.
After the configuration is completed, test: win+R -> java -version When you see the following information, it means ok
Note: (1) Do not create a new JAVA_HOME in the Administrator variable, and then add %JAVA_HOME%\bin after the Path of the system variable.
(2) %JAVA_HOME%\bin should not be written as %JAVA_HOME\bin
