In Java ArrayList, Write a static method called flip2 that takes an ArrayList of Strings as a parameter and then flips each successive pair of values in the list. For example, suppose that a variable called list stores the following sequence of values: [aa, bb, cc, DDD, happy, snow] and we make the following call: flip(list); Afterwards the list should store the following sequence of values: [ bb, aa, DDD, cc, snow, happy] If the list has extra values that are not part of a pair, those values are unchanged. For example, if the list had instead stored: [aa, bb, cc, DDD, happy, snow, hometown] The result would have been: [ bb, aa, DDD, cc, snow, happy, hometown]
