Sounds like you need to parse the file with some sort of regular expression to match the pattern you are after. java.io.* and java.util.regex.* should help.
This is tricky, as there is no one particular string you can look for. Even using regexps there are quite few possibilities of how a main method might look like. It would be easier to do this with class files instead of source files, since you can use reflection to look for the one signature that indicates a main method.
