How do I generate n classes after compiling?

Get a bag and wrap it up.

Add the package name to the first line of the source file, as follows:

 Package mymenu;

Recompile with the following command:

C:\users\zhangbz\desktop\demo>javac-d. Mymenutest.java

After recompiling, the generated class files are saved under the MyMenu folder in the current directory

Then specify the class with the main function to execute when you double-click the jar package:

Add a file (the file name is optional) in the directory where the MyMenu folder is located, specifying Main-class:

Main-class:mymenu. Mymenutest

Requirements: ":" Must have a space, the end of the line must have a carriage return, indicating the end of a line of input.

Finally, the following command is repackaged:

1. txt mymenu

Now that you are done, you can double-click the jar package to execute the Java program.
