Java: Wrapper Types and Autoboxing
Answer
Autoboxing can cause unexpected performance issues and NullPointerExceptions.
Autoboxing is automatic conversion between primitives and wrappers. It adds overhead, especially in loops, and can lead to NullPointerExceptions. Consider 'Integer total = 0;', where 'total += null;' throws an exception. Always check for nulls to avoid such pitfalls.
