Instructions Write two public static methods in the U6_L4_Activity Two class. The first should have the signature SnapCintar, int t, int and return type vold. This method should swap the values at the indices i and j of the array arr (precondition: i and jare both valid indices for arr). The second method should have the signature all SwapCintarr) and return type void. The precondition for this method is that are has an even length. The method should swap the values of all adjacent pairs of elements in the array, so that for example the array {3.5.2, 1.8, 10) becomes (5, 3, 1, 2,10,8) after this method is called. Use the runner class to test this method: do not add a main method to your code in the U6_L4 Activity. Twojava file or it will not be scored correctly.
