Java - Wrapper Classes

Why does autoboxing sometimes cause performance issues in Java?

ABecause autoboxing creates new wrapper objects frequently, increasing memory and CPU usage.

BBecause autoboxing disables garbage collection.

CBecause autoboxing converts primitives to strings internally.

DBecause autoboxing requires explicit casting.

Step-by-Step Solution

Solution:

Step 1: Understand autoboxing overhead
Autoboxing creates wrapper objects for primitives, which can add memory and CPU overhead if done repeatedly.
Step 2: Evaluate other options
Options A, B, and D are incorrect because autoboxing does not convert to strings, disable garbage collection, or require casting.
Final Answer:
Because autoboxing creates new wrapper objects frequently, increasing memory and CPU usage. -> Option A
Quick Check:
Autoboxing can impact performance due to object creation [OK]

Quick Trick: Avoid excessive autoboxing in performance-critical code [OK]
