Create an application containing an array that stores eight integers. the application should call five methods that in turn (1) display all the integers, (2) display all the integers in reverse order, (3) display the sum of the integers, (4) display all values less than a limiting argument, and (5) display all values that are higher than the calculated average value. save the file as arraymethoddemo. java.
