Java - Arrays

Identify the error in this Java code snippet:

int[] data = new int[5];
System.out.println(data.length());

AArray length property does not exist in Java

BArray size must be declared with curly braces, not square brackets

CThe array must be initialized with values before accessing length

DArray length is accessed with parentheses, causing a compile error

Step-by-Step Solution

Solution:

Step 1: Check how length is accessed
The code uses data.length() with parentheses, but length is a property, not a method.
Step 2: Confirm correct syntax
The correct way is data.length without parentheses. Using parentheses causes a compile-time error.
Final Answer:
Array length is accessed with parentheses, causing a compile error -> Option D
Quick Check:
length is a property, no parentheses [OK]

Quick Trick: Remember: length is property, no () [OK]
