Assume the method doSomething has been defined as follows: public static void doSomething (int[] values, int p1, int p2) { int temp = values[p1]; values[p1] = values[p2]; values[p2] = temp; } What does the method do? Group of answer choices

a. It inserts a new value into the array values.

b. It swaps the integer values stored in positions p1 and p2 of the array values.

c. It copies the integer array values to a new array.

d. It moves each element of the array values to a higher index position.

The answer to this question is option "b".

Explanation:

In the method definition, we perform swapping. To perform swapping we define a variable "temp" that swap values of variable p1 and p2 and store in array that is "values". and other options are not correct that can be defined as:

In option a, It does not insert any new value in array because we do not pass any value in function. In option c, The function does not copy and assign a value in a new array because in this function we not assign any new array. In option d, It is incorrect because it can not move an element into high index position.
