Question: 1 / 510

What is a benefit of using wildcard generic types in Java?

They can directly hold primitive types

They improve the runtime efficiency of the program

They enable the code to operate on a broader range of types

Wildcard generic types in Java allow for more flexibility in the types of data that can be used in code. They can handle both specific types and broad types, making it easier to write reusable code that can work for a wider range of data. The other options are incorrect for the following reasons

A) Wildcard generic types cannot directly hold primitive types, as they only work with classes and interfaces.

B) There is no difference in runtime efficiency when using wildcard generic types compared to regular type parameters.

D) Wildcard generic types do not provide stricter compile-time type checking compared to regular type parameters. In fact, they offer less type safety and can potentially cause unchecked warnings.
