☕🎓JAVA CERTIFICATION QUESTION: Collections and generics

· java,ocp

Which data structure among the following lacks the utilization of generics?

* Array

* List

* Map

* Queue

* Set

* Vector

#java #certificationquestion #ocp


Arrays do not employ generics.

Unlike other data structures like Set, List, Map, Queue, and Vector, which can utilize generics to enforce type safety and flexibility, arrays in Java are covariant and invariant, meaning they can store elements of any type but do not have built-in type checking at compile-time.

Therefore, arrays can potentially lead to runtime errors if incorrect types are inserted into them.

This lack of type safety is a notable distinction from the other data structures listed.
