Hi, I'm working on a programming assignment. As I tried to run PercolationVisualizer.java (it will draw grid) with an argument, an error appeared:

Apparently all the files inside percolation/.idea/fileTemplates/internal/ directory have the above error.

Thanks in advance

Your project source roots are misconfigured. .idea directory must not be located under the source root. Otherwise javac will try to compile files in this directory.
