What is Predicate and how to use it in Java 8
The Predicate interface in Java is a functional interface introduced in Java 8 as part of the java.util.function package. It represents a single argument function that returns a boolean value. The Predicate interface is often used for filtering or matching conditions in streams and collections.
Key Points:
Functional Interface: It has a single abstract method, making it a functional interface suitable for lambda expressions and method references.
Method: The primary method is test(T t), which evaluates the predicate on the given argument.
Default Methods: It includes default methods like and, or, and negate for combining predicates.
