Exercise : equals

Write a method named equals that accepts two arrays of integers as parameters and returns true if they contain exactly the same elements in the same order, and false otherwise. Note that the arrays might not be the same length; if the lengths differ, return false. Do not call Arrays.equals in your solution.

For example, if the following arrays are declared:

int[] a1 = {10, 20, 30, 40, 50, 60};
int[] a2 = {10, 20, 30, 40, 50, 60};
int[] a3 = {20, 3, 50, 10, 68};

The call equals(a1, a2) returns true but the call equals(a1, a3) returns false.
