My professor asked me to write a java program that will pull comments from another java file and display in a .txt file. I wrote the program and tested to make sure it works but he still gave me a 0 for my score. The reason for this is he said there is a required main class: CScrape. I am confused and am not sure what he means by that. Ill attach a picture of my program.
