Java - Arrays

Why is it important to use i < array.length instead of i <= array.length when traversing arrays in Java?

ABecause array indices start at 0 and go up to length - 1

BBecause array length is always one less than the number of elements

CBecause using <= causes the loop to skip the last element

DBecause Java arrays are 1-indexed

Step-by-Step Solution

Solution:

Step 1: Understand array indexing
Java arrays start at index 0 and end at index length - 1.
Step 2: Explain loop condition
Using i <= length tries to access index length, which does not exist and causes error.
Final Answer:
Because array indices start at 0 and go up to length - 1 -> Option A
Quick Check:
Array index range = 0 to length - 1 [OK]

Quick Trick: Array indexes go from 0 to length - 1 [OK]
