this is the code i have so far. please finish the methods will give thumbs up

\} 3) A test file (ArrayListStackTest.java) with default method bodies for each of the stack methods will be created in the Test Packages folder. You will have to edit these default method bodies to write your test cases. You may comment out or delete the test case for toString() - you do not have to test that method but you can if you want to. Make sure that: a) You delete the throws Exception from the testPop and testPeek method definitions. This will force you to use try-catch blocks in the test methods rather than throwing the exception to the calling method. These try-catch blocks are required. You will have to import those Exceptions. b) Your tests appropriately exercise your code to verify that all methods work for standard, edge, and error cases and that the contents of the stack (and size/count field) are correct as a result of executing that method. c) Exceptions are caught and their results verified. d) All your tests pass before moving on. For each default method body, leave the lines printing the name of the method being tested and setting up the initial stack but remove or replace the remaining ones with your own code. Don't assume that the default test body NetBeans generated is the best or only way to test a method; it's just a generic NetBeans test body and is guaranteed to be incomplete. When setting up the initial stack, remember that since ArrayListStack is generic so you will have to decide the data type of objects stored in this stack and create appropriate stack objects to test your code. The test cases assume your objects are of data type Object but you must replace that with a more specific object data type (perhaps String or Integer; your choice)
