Quizplus · Accepted Answer

Java performs auto-boxing when an integer literal is added to an ArrayList<Integer>. Auto-boxing is the process of automatically converting a primitive data type (such as int) to its corresponding object wrapper class (such as Integer). In this case, the integer literal is automatically converted to an Integer object before being added to the ArrayList.
