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.
This is a guide to Java Predicate. Here we discuss an introduction to Java Predicate, syntax, how does it work, with programming examples. You can also go through our other related articles to learn more – Java 9 Features Functional Interface in Java JavaFX Libraries Java Parallel Stream...
2. Predicate not() Method – Java 11 In Java 11,Predicateclass has a new methodnot(). It returns aPredicatethat is the negation of the supplied predicate. Internally, this is accomplished by returning the result of the callingpredicate.negate(). Predicate<Integer>isEven=i->i%2==0;Predicat...
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.
