Write a Java program that has a method called append that accepts two integer arrays as parameters and returns a new array that contains the result of appending the second array's values at the end of the first array. For example, if arrays list1 and list2 store {2, 4, 6} and {1, 2, 3, 4, 5} respectively, the call of append(list1, list2) should return a new array containing {2, 4, 6, 1, 2, 3, 4, 5}. If the call instead had been append(list2, list1), the method would return an array containing {1, 2, 3, 4, 5, 2, 4, 6}.
