define a method named swapvalues that takes an array of four integers as a parameter, swaps array elements at indices 0 and 1, and swaps array elements at indices 2 and 3. then write a main program that reads four integers from input and stores the integers in an array in positions 0 to 3. the main program should call function swapvalues() to swap array's values and print the swapped values on a single line separated with spaces. ex: if the input is: 3 8 2 4 function swapvalues() returns and the main program outputs: 8 3 4 2 the program must define and call a method: public static void swapvalues(int[] values)
