Quizplus · Accepted Answer

Generic types are erased during compilation and do not exist at the byte code level. The code that is generated by the Java compiler uses raw types in place of generic types. Raw types are classes that have not been parameterized with type arguments. Therefore, option B and C are incorrect. A generic class can be abstract, so option D is also incorrect.
