How to run Java program from any arbitrary directory inside Terminal

Question

I saw some other similar posts, but they didn't seem to answer my question.

I have a package of java files, and the java functions inside one file call java functions from a different file. Right now I am limited to run my program from the parent directory of gitlet as shown in the screenshot. Is there a way to run my java program from any arbitrary directory?

PS I am hoping to get a solution that can be done just inside terminal.

Yes, you can add the base directory that contains the compiled .class files to the CLASSPATH environment variable.
