[Solved] Identify the error in this array traversal code:int[] data = {2, 4, 6}; for(int i = 0; i — Ans: Loop condition should be i < data.length, not <= data.length | Java

Java - Arrays

Identify the error in this array traversal code:

int[] data = {2, 4, 6};
for(int i = 0; i <= data.length; i++) {
  System.out.println(data[i]);
}

ASystem.out.println should be outside the loop

BArray declaration is incorrect

CLoop condition should be i < data.length, not <= data.length

DNo error, code runs fine

Step-by-Step Solution

Solution:

Step 1: Analyze loop condition
The loop runs while i <= data.length, which means i can be equal to data.length (3).
Step 2: Check array index access
Accessing data[3] causes ArrayIndexOutOfBoundsException because valid indices are 0 to 2.
Final Answer:
Loop condition should be i < data.length, not <= data.length -> Option C
Quick Check:
Index must be less than length to avoid error [OK]

Quick Trick: Use i < length, not i <= length in loops [OK]
