Exploring Generics in Java: Explaining the Extends Wildcard Boundary | Generics in Java

Welcome to our Java tutorial series! In this video, we'll delve into the concept of the extends wildcard boundary in Java Generics. By the end of this tutorial, you'll have a thorough understanding of how the extends wildcard boundary is used in Java programming.

The extends wildcard boundary in Java Generics allows you to specify a range of types that are allowed as arguments in a generic method or class. It is represented by the "? extends T" syntax, where "T" is the upper bound type. This wildcard boundary is useful when you want to accept any type that is a subtype of a particular class or interface.

In this tutorial, we'll cover:

1. An introduction to the extends wildcard boundary in Java Generics and its significance.
2. Explanation of the syntax and usage of the extends wildcard boundary in generic methods and classes.
3. Understanding the relationship between the extends wildcard boundary and inheritance in Java.
4. Practical examples demonstrating how to use the extends wildcard boundary to create more flexible and reusable code.
5. Best practices and considerations for using the extends wildcard boundary effectively in your Java projects.

By the end of this video, you'll be equipped with the knowledge and skills to understand and utilize the extends wildcard boundary in Java Generics, enabling you to write more versatile and adaptable code.
