Java - Arrays

Which of the following for loops correctly traverses the array int[] arr from start to end?

Afor(int i = 0; i < arr.length; i++) { System.out.print(arr[i]); }

Bfor(int i = 1; i <= arr.length; i++) { System.out.print(arr[i]); }

Cfor(int i = arr.length; i > 0; i--) { System.out.print(arr[i]); }

Dfor(int i = 0; i <= arr.length; i++) { System.out.print(arr[i]); }

Step-by-Step Solution

Solution:

Step 1: Understand array indexing
Array indices start at 0 and go up to length-1.
Step 2: Check loop conditions
Loop must run from 0 to less than arr.length to avoid IndexOutOfBoundsException.
Final Answer:
for(int i = 0; i < arr.length; i++) { System.out.print(arr[i]); } -> Option A
Quick Check:
Loop uses i < arr.length, correct indexing [OK]

Quick Trick: Use i < array.length for safe traversal [OK]
