oi... The error is right infront of you.

javac: file not found: WordCount.java

If the file isn't found then your are not specifying it correctly, try using the absolute path to the file and not just a file name. File names are going to be searched(in general) against your $PATH shell variable and if it is not in one of those folders it won't find it.
