What workaround does Java provide for the inability to use primitives as type parameters?

  1. Type conversion

  2. Autoboxing and auto-unboxing

  3. Dynamic casting

  4. Extended generics

The correct answer is: Autoboxing and auto-unboxing

Java provides a workaround for the inability to use primitives as type parameters by using autoboxing and auto-unboxing. This is done by automatically converting between primitive types and their corresponding wrapper classes (Boolean, Character, Integer, etc). Type conversion (option A) is the process of converting a variable from one data type to another, and is not related to the use of primitives as type parameters. Dynamic casting (option C) is used to dynamically change the type of a variable at runtime, and has no relation to using primitives as type parameters. Extended generics (option D) refers to Java's generic type system which allows for the use of type parameters in classes, interfaces, methods and constructors, and does not specifically provide a workaround for using primitives as type parameters.
