JDK
Install the JDK website: Software Download | Oracle
At present, the latest ones are 20 and 17. I feel that there are relatively few information on the Internet for 20, so it is better to install 17~
download exe file
In this way, the installation is complete, enter the C drive to see
Click "Close", and then configure the environment variables. Right-click "This PC" and select Properties, then a pop-up window will appear, click "Advanced System Settings".

Select the environment variable, select the "New" option under "System Variables", the variable name is JAVA_HOME, and the variable value is the installation path of JDK
After the input is complete, click Confirm, the first configuration is completed, and then proceed to the second step
Select the "New" option under "System Variables". The variable name is "CLASSPATH. The variable value is: .;%JAVA_HOME%\lib;%JAVA_HOME%\lib\tools.jar (note that there is a point in front), configure After that, the following picture can be copied and pasted here.
Then click OK to save the variable and go to the third step.
Find the variable path in the environment variable and double-click to open it. Then you can see that there are already a lot of content in the path, we create a new one at the end:
Add %Java_Home%\bin;%Java_Home%\jre\bin; at the beginning of the variable value

type javac
Enter java -version
Sincerely, the JDK configuration is complete!
