Answer
Repeated autoboxing can cause performance issues and subtle bugs.
In a loop, autoboxing creates many unnecessary objects, leading to inefficient memory usage. This can also introduce subtle bugs if relying on object equality. For example, summing an Integer list can inadvertently use boxed values, resulting in unexpected behavior.
