P61 - Interfaces in Java - Part 2 | Core Java | Java Programming |

Functional interfaces play a crucial role in Java's functional programming paradigm. In this video, we explore the concept of functional interfaces and their significance in writing concise and expressive code.

We discuss what functional interfaces are and how they enable the use of lambda expressions and method references. We showcase popular functional interfaces from the Java standard library, such as Predicate, Consumer, Function, and Supplier, and demonstrate how they can be leveraged to solve common programming challenges.

Furthermore, we discuss the @FunctionalInterface annotation and its role in ensuring the interface adheres to the functional programming contract.

By the end of this video, you'll have a solid understanding of functional interfaces in Java and be equipped with the knowledge to leverage them effectively in your own code.

Whether you're a beginner or an experienced developer seeking to gain in-depth knowledge on java, this video will provide valuable insights into the power of functional interfaces in Java.

Points covered in this video:
❇️ What is a functional interface?
❇️ When it is introduced & why it is introduced?
❇️ How to define & implement the functional interface?
❇️ Can we have more than one method in the functional interface?
❇️ How anonymous classes are helping in implementing the functional interfaces?

[yanamalavenkatesh]

Bro miru cheppindi koda thappe.... non abstract method antey normal method koda vasthadi... the right definition is... a functional interface is a interface which should have max of 1 abstract method and n number of default and static methods is the right definition and you didn't covered the functional interfaces which we have before java 8....

[kvkcreations]

Would you please try to make videos on Regular Expressions topic.

[Anu_ECE]

Sir, in the functional interface does not allow private access specifier
Public, abstract, default, static and strictfp are allowed in the functional interface

[Bhavananani]

Hello can you make videos on spring boot , maven Projects .so that we can have more ideas on those topics as well
