IntPredicate

Description: IntPredicate is a functional interface in Java that represents a predicate, meaning a function that takes an int argument and returns a boolean value. This interface is part of the java.util.function package, introduced in Java 8 as part of the implementation of lambda expressions and functional programming in the language. The main feature of IntPredicate is its ability to operate on primitive int values, which avoids the need for autoboxing and improves performance compared to using the Predicate interface. As a functional interface, IntPredicate can be used as the target of a lambda expression or a method reference, allowing for more concise and readable syntax. Its main abstract method, test(int value), evaluates the provided integer value and returns true or false, depending on whether it meets the condition defined in the predicate’s implementation. This interface is particularly useful in filtering operations, validation, and conditions on data collections, where evaluating conditions on integer values efficiently and clearly is required.
