Assume numbers is an int array that is currently filled with the following values: 9 12 4 8 20 15 3 What is the value of numbers[numbers.length-2] after the testMethod(numbers) is executed? public static void testMethod (int[] array) { for (int i=0; i array[array.length-i-1]) array[i]=array[array.length-i-1]; } Given int[] numbers=(9, 12, 4, 8, 20, 15, 3) and a method defined as follows, what is numbers[0] after testMethod(numbers) is called? public static void testMethod (int[] array) { for (int i=array.length-1; i>0; i--) array[i]=array[i-1]; } What does the following method do? public static int testMethod (int[] array) { int var=0; for (int i=0;i
