Java 8 Predicate with Examples [toc] A Functional Interface is an Interface which allows only one Abstract method within the Interface scope. There are some predefined functional interface in Java like Predicate, consumer, supplier etc. The return type of a Lambda function (introduced in JDK 1.8)...
3. UsingPredicatewith Java 8 Stream As we know, thePredicateis afunctional interface, meaning we can pass it in lambda expressions wherever a predicate is expected. For example, one such method isfilter()method from theStreaminterface.
The Java 8 Predicate is largely tied to functional programming, but it doesn't have to be. Here are some examples with lambdas to get the most out of the component and reduce the verbosity of your code.
Java examples of chained predicates and to perform ‘logical AND‘ and ‘logical OR‘ operations and collect the elements into a list. Negating a Predicate in Java Java 8 predicate negate() returns a predicate that is the logical negation of this predicate. Java 11 introduced not() which is...

Thus, using these methods with the predicate helps in evaluating any of the conditions defined with the predicate’s method types. Examples to Implement Java Predicate Below are examples mentioned: Example #1 This program demonstrates the creation of a simple Predicate and then calling that Predicate...
