Write a generic class called "MyFour". It should use a type parameter of "T". It should have four fields, item1, item2, item3, item4, all of type T. Its constructor receives values for setting all four items. It should have a method "allEqual" that returns true if all four items are equal according to their "equals" method. It should have a method called "shiftLeft" that shifts all items up one position, and puts the first item's value into the last item.
For example, if list has 1, 2, 3, 4, then after shiftLeft, it is 2, 3, 4, 1.
It should have a "toString" method that returns a String of the items in this format: (item1, item2, item3, item4).
Finally, add a "main" method. First it should create a MyFour object of type String, passing it four identical strings. Print the object, then call and print the results of "allEqual". Next, create an object of four different Integers. Again print the object and print the results of "allEqual". After that, shift the items left using your method, and print them again.
