Functional Interfaces in Java | Consumer | Supplier | Function | Predicate
Learn everything you need to know about Functional Interfaces in Java! In this video, I explain what functional interfaces are, how to create a custom functional interface, and how to use the most common built-in ones:
✅Consumer - performs actions on inputs
✅Supplier - provides values without input
✅Function - transforms input to output
✅Predicate - tests a condition and returns a boolean
Whether you're preparing for a Java interview or looking to improve your Java functional programming skills, this tutorial will help you understand these concepts clearly with hands-on examples.
