Class ArrayTest contains main() method declare array a[5] declare array b[5]

1. Class ArrayTest contains main() method declare array a[5] declare array b[5] initialize both array with data invoke method addArray() collect the array return by this method print the returned array by invoking printArray() method Class ArrayMethod addArray(array 1, array 2) adds array 1 and array 2 returns an array printArray(array) prints array returns nothing Programming Problem: Passing and Returning Array to/from a Method Write Java code to define the class “ClassArrayMethod”. Then use the methods of this class in the driver class “ClassArrayTest” according to the specifications given below:
