Java - Memory Management Basics

ASet object references to null when no longer needed inside the loop

BCall System.gc() inside every loop iteration

CIncrease heap size to avoid garbage collection

DAvoid creating any objects inside the loop

Step-by-Step Solution

Solution:

Step 1: Identify best practice for efficient memory use in loops
Many temporary objects in a loop can pressure memory; explicitly setting references to null when no longer needed helps the GC identify and free them sooner. Frequent System.gc() is inefficient and not guaranteed; larger heap delays issues; avoiding all objects may not be feasible.
Final Answer:
Set object references to null when no longer needed inside the loop -> Option A
Quick Check:
Null references help GC free memory efficiently [OK]

Quick Trick: Nullify unused references to help garbage collection [OK]

Common Mistakes:

Calling System.gc() too often expecting instant cleanup
Thinking increasing heap size solves memory leaks
Believing you must avoid all object creation in loops
