Write a java program that creates a driven menu program to perform methods?

The methods are 1)summing the elements of an array 2)finding the largest value in an array 3)finding the largest difference between two element of the array. 4)Locate a key value in an array 5)double the values in an array 6)compare two array that contain the same values but not in the same order in which the value

Try to do your own homework first then ask if you have any problems.

I did but my teacher said that I was supposed to create an object and a method. I used a switch case statement and it had the same output. I don't know how u would do it with an object. I already have done the code for the menu but my problem is how to put that in an object and have it print out the results in a switch case statement.

I had to put the code in separate replies because all of the code couldn't fit in one.
