• Directory of executable files under PATH:JDK (%java_home%\bin;%java_home%\jre\bin;)
• Classpath:java the directory where the runtime needs to find the class file (.; %java_home%\lib;)

6) Testing the Java development environment is normal, in general there are two ways:

The first: direct cmd opens the command-line window, running: java-version , the installed Java version information appears as described in the correct configuration:

The second type: Write a Java program under the specified directory, compile it using the Javac command at the command line, and run it using the Java command, so that the desired result of the program is configured correctly;
