Program Error
Dear Sir, I have the latest version of eclipse. In the video clip the speaker has removed the static main method. Wheras in my computer it prompts me saying that there is an error in the program, and to add the static main method.In the next video(Instance Fields) (somewhere around 6-7 minutes) she runs the program,and it prints the statments, but when I did it, it showed me error.Please help me.
