Open up Eclipse and create a new class called ArrayListPractice.java Next, copy and paste the below program into your file and run the code. Your job is to take the given code, remove all the arrays and replace them with the identical ArrayLists. There should be no arrays in your program. You will need to call the ArrayList methods as defined in the lesson notes above. Note that you will not be able to do method overloading with ArrayLists so you should assign different names to your methods. Once you have made the changes, you should get identical output as the given version of the program. Submit your program when you are finished.
