JAVA: Please help with the following problem

Study the supplemental Module materials on "Stack and Queue Data Structures", and search online if you can find built-in classes in Java for such structures. You should find information relating to java.util.Stack and java.util.Queue , and use some examples to help you create two java applications that utilize built-in methods of the Stack and Queue classes, one is using the stack data structure and the other is using the queue data structure.
