Practice

Define the output for the following code fragments.

int arr[] = { 2, 7, 7, 4, 2, 6, 9 };

a) for (int i = arr.length-1; i > 0; i--)

System.out.println(arr[i]);

b) for (int i = 0; i < arr.length; i+=2)

System.out.println(arr[i]);

c) for (int i = 0; i <= arr.length; i++)

System.out.println(arr[i]);

d) for (int i = 1; i < 4; i++)

System.out.println(arr[i+1] + 1);

e) for (int i = 1; i <= arr.length; i++)

System.out.println(arr[i-1] - 1);
