What is a Function Interface ?

The Java Function Interface (JFI) is one of the most powerful and versatile components of the Java programming language. It allows developers to create custom functional interfaces, which can be used as the basis for a wide range of programming applications. As a result, understanding the Java Function Interface can be invaluable for both experienced and novice Java developers. In this blog post, we’ll explore the basic concepts of the Java Function Interface and discuss how to make the most of its capabilities. We’ll also look at some of the common use cases for the JFI, as well as some of the challenges associated with using it. Ultimately, this post will provide a better understanding of the Java Function Interface and how it can be used to create reliable, robust, and powerful applications.
