What Is A Functional Interface? In this informative video, we’ll clarify the concept of functional interfaces in Java and their importance in programming. We’ll begin by explaining what a functional interface is and how it is defined by having a single abstract method. You’ll learn about the role of lambda expressions in simplifying code and how they relate to functional interfaces.

We’ll provide examples to illustrate how to implement a functional interface using lambda expressions, making it easier to write concise and readable code. Additionally, we’ll explore the various predefined functional interfaces available in the java.util.function package, detailing their specific purposes and use cases.

This video will also highlight practical applications of functional interfaces, such as in event handling and stream processing, showcasing their versatility in real-world programming scenarios. By the end of this video, you’ll have a solid understanding of functional interfaces and how they enhance your coding practices.
