Installation process

After downloading, double-click to enter the installation. The version I installed is jdk1.8. If you need it, please contact me in the comment area.

 Next, follow the steps. The installation path here can be changed. I personally recommend not to change it, just use the default installation address. It is not very big, so just keep going to the next step.

Environment configuration

After the installation is completed, the next step is to configure the environment. Right-click My Computer (This Computer) to find Properties and enter to find Advanced System Settings.

Click to enter and find the environment variables.

 Then in the system variables column, create a new variable.

1. Configure CLASSPATH

Variable name: CLASSPATH

Variable value: .;%JAVA_HOME%\lib;%JAVA_HOME%\lib\tools.jara

Then click Confirm

2. Configure JAVA_HOME

Variable name: JAVA_HOME

Variable value: C:\Program Files (x86)\Java\jdk1.8.0_201, Note: This value is the path to install jdk yourself.

3. Configure Path

Click Edit, then create new, add %JAVA_HOME%\bin, %JAVA_HOME%\jre\bin respectively

At this point the environment is configured.

Check whether the configuration is successful

Win+R opens Run, enter cmd, and enter the terminal.

 

Enter Java -version and press Enter. You can see a version number, indicating that the configuration is successful.
