15.11.1. Generic Class

Try these first

1. 1.

   What is a generic class?

   Hint

   Think of it as a class that can handle different data types.

2. 2.

   Define a type parameter in the context of generics.

   Hint

   Look for the angle brackets in class definitions.

3. 3.

   What is the primary purpose of a generic class?

   • To improve performance
   • To enable type-safe operations
   • To simplify class creation

   Hint

   Consider what generics aim to reduce in coding.

4. 4.

   True or False: Generic classes can only handle a limited number of types.

   • True
   • False

   Hint

   Think about how many types a generic class can work with.

5. 5.

   Design a generic class called Pair that holds two values of possibly different types. Implement methods to set and get these values.

   Hint

   Consider how you will manage two different type parameters.

6. 6.

   Write a main method that creates a Pair of an Integer and a String. Set the values and print them out.

   Hint

   Remember to use the generic class with actual types in the instantiation.
