Java programming Create an application containing an array t

Java programming:

Create an application containing an array that stores 10 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. Then, create another array that store 5 integers. Pass the two arrays to a method that will display the integer value(s), if any, that appear in both arrays (note that the two arrays can have no stored values in common).

OUTPUT:

(1) display all the integers:
(2) display all the integers in reverse order:
12 32 43 54 11 42 22 21 43 13
(3) display the sum of the integers:
13 43 21 22 42 11 54 43 32 12
(4) display all values less than a limiting argument 5 :
12 32 43 54 11 42 22 21 43 13
(5) display all values that are higher than the calculated average value:
32 43 54 42 43
