Assume that you have an array of integers named arr. Which of these code segments print the same results? int i = 0; while (i < arr. length) { System. out. println (arr[i]); i++; } int i; for (i = 0; i < = arr. length; i++) { System. out. println (arr[i]); } for (int i : arr) { System. out. println (i); }

2. int i; for (i = 0; i < = arr. length; i++) { System. out. println (arr[i]); }

3. for (int i : arr) { System. out. println (i); }

second and third code segments print the same output.

Explanation:

In first code segment, while loop starts printing from arr[0] and it continues till the second last element of the the array as in statement of while loop i
In second code, for loop starts from 0 and ends at the last element of the array. which prints from arr[0] to arr[length].

In third code segment, it also print from arr[0] to arr[length]. In this case for (int i : arr) means start from first value of array and continues till last element of the array.
