Java: Wrapper Types and Autoboxing
Answer
Look for primitives being assigned to wrapper collections or method calls.
Autoboxing occurs when a primitive is added to a collection or passed to a method expecting a wrapper. For example, 'List prices = new ArrayList(); prices.add(29.99);' autoboxes '29.99' to 'Double'.
