Discord Community:   / discord   GitHub Repository: https://github.com/geekific-official/ Java 8 brought a ton of new features with it. One of these features is a powerful new syntactic improvement in the form of lambda expressions. A lambda, is an anonymous function defined at the level of special interfaces. These interfaces are what we call functional interfaces. In this video, we dive in the most important functional interfaces provided by Java, and come up with multiple examples for each of them.
