any idea how to put this code in without getting the could not load or find main class file? I run javac Frown.java in compiler which creates the Frown.class file but prompts the error could not find or load main class when I run attempt to run the .class file. I am simply only trying first page and I cant get the first chernoff face code to run. There are a total of 4 in the file linked and I don't know what in class path I am doing wrong
