    Where is the class ArrayComparator defined? The compiler can not find its definition.
    If you don't understand my answer, don't ignore it, ask a question.

    That link doesn't look like it is part of the Java SE API.
    See: Java Platform SE 7

    If you want to use some third party classes, you need to put their definitions on the classpath when you compile and when you execute the code that uses them.
    If you don't understand my answer, don't ignore it, ask a question.
