Check whether the Java file is changed? Check what?
Maybe you mean check whether the Java file is newer than the class file? You'd just use the operating system's last modified time for the two files. If you're doing this in Java, the java.io.File class has a method to check this; otherwise, "ls -l" or "dir" will do the trick.
