numbers[0] = 5;
numbers[1] = 10;
System.out.println(numbers[2]);

B5

C0

DArrayIndexOutOfBoundsException

Step-by-Step Solution

Solution:

Step 1: Analyze array initialization and assignments
Array 'numbers' has size 3. Index 0 is set to 5, index 1 to 10. Index 2 is not assigned explicitly.
Step 2: Determine default value at index 2
Since index 2 is not assigned, it holds default int value 0. Printing numbers[2] outputs 0.
Final Answer:
0 -> Option C
Quick Check:
Unassigned int array element = 0 [OK]

Quick Trick: Unassigned int array elements default to 0 [OK]
