So I want to create a function that does all this for me (and gets rid of the class files afterwards). The code below is my attempt. Could someone let me know how I can fix my code?

of changing directories you use the classpath (-cp) option to tell Java
where to find the Main class. E.g.

:!java -cp %:p:h Main
