Why Generics Matter
Explain the benefits of generics in Java, focusing on type safety, code reusability, and reduced type casting. Include at least two examples where generics prevent runtime errors.
Implement a Generic Box Class
Create a generic class Box<T> with set(T value) and get() methods. Test it with String, Integer, and Double values to demonstrate type-safe reuse.
Create and Use Generic Methods
Write a utility class containing a generic method to print any array and another generic method to return the maximum of three comparable values.
Practice Generic Constructors
Create a class with a generic constructor that accepts different data types and stores or prints them. Instantiate the class with at least three different argument types.
Generics with Polymorphism
Write a Java program using a generic method with wildcard bounds (for example List<? extends Number>) and demonstrate how polymorphism works with different numeric wrapper types.
