What is a Predicate Interface ?

The Java Predicate Functional Interface is an incredibly powerful tool for enhancing your Java code. It is a part of the Java 8 API, and is a functional interface with a single abstract method. This method, test(), is used to evaluate a boolean expression and returns a boolean value. The Predicate Functional Interface offers a range of advantages, from improved coding performance to greater readability. It allows you to work with a range of different data types, including primitives, objects, and class instances. Additionally, by using the Predicate Functional Interface, you can use a single function call to perform multiple tests, making your code more efficient. In this blog post, we will explore the Java Predicate Functional Interface in detail, discussing its features, benefits, and how to use it effectively. We will also look at some of the common use cases for this interface, including filter collections and applying a condition to a stream.
