Answer:

Explanation:

rite a method named swapPairs that accepts an array of strings as a parameter and

switches the order of values in a pairwise fashion. Your method should switch the order

of the first two values, then switch the order of the next two, switch the order of the next

two, and so on. For example, if the array initially stores these values:

String[] a = {"four", "score", "and", "seven", "years", "ago"};

swapPairs(a);

Your method should switch the first pair ("four", "score"), the second pair ("and", "seven") and

the third pair ("years", "ago"), to yield this array:

{"score", "four", "seven", "and", "ago", "years"}

If there are an odd number of values, the final element is not moved. For example, if the

original list had been:

{"to", "be", "or", "not", "to", "be", "hamlet"}

It would again switch pairs of values, but the final value ("hamlet") would not be moved,

yielding this list:

{"be", "to", "not", "or", "be", "to", "hamlet"}
