Learn to debug. Add some print statements so you can trace the execution of
your program. Attach a debugger. If nothing happens, that's because your app
did nothing. Java will print an error message if it finds a problem.

I added the following as the first executable statement (etc) in the project:

System.out.println("Hello 1");

I then ran the project on my friend's PC using the Command Prompt and the command: java testing.jar

I received the error message:

Exception in thread "main" java.lang.NoClassDefFoundError: testing/jar

Well give that the java command is in the format:

java -classpath myprog.jar mypackage.MyClass

or:

java -jar myprog.jar

then that is not surprising.
