Answer 1

You cannot run JavaProgramming.java with CD.

Files with .java extensions are not compiled programs. You need, first of all, to compile it with some compiler, like javac. It will generate a .jar file.

After that, you can use the java command in the terminal to run this program. Example: java ./JavaProgramming.jar
