Assume an array of integers named arrNum has been properly declared and initialized. Which of these code segments will result in displaying the same output? (4 points)

1.

int i = 0; while (i < arrNum.length) { System.out.println(arrNum[i]); i++; }

2.

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

3.

for (int a : arrNum) { System.out.println(a); }

	I and II only
	II and III only
	I and III only
	All three print the same results.
	All three print different results.
