Uses of Interface java.util.function.Predicate (Java SE 11 & JDK 11 )

Packages that use Predicate
Package	Description
java.util	Contains the collections framework, some internationalization support classes, a service loader, properties, random number generation, string parsing and scanning classes, base64 encoding and decoding, a bit array, and several miscellaneous utility classes.
java.util.concurrent	Utility classes commonly useful in concurrent programming.
java.util.function	Functional interfaces provide target types for lambda expressions and method references.
java.util.regex	Classes for matching character sequences against patterns specified by regular expressions.
java.util.stream	Classes to support functional-style operations on streams of elements, such as map-reduce transformations on collections.

Uses of Predicate in java.util.function

Methods in java.util.function that return Predicate
Modifier and Type	Method	Description

Uses of Predicate in java.util.regex

Methods in java.util.regex that return Predicate
Modifier and Type	Method	Description
`Predicate<String>`	Pattern.`asMatchPredicate()`	Creates a predicate that tests if this pattern matches a given input string.

Uses of Predicate in java.util.stream

Methods in java.util.stream with parameters of type Predicate
Modifier and Type	Method	Description
`boolean`	Stream.`allMatch(Predicate<? super T> predicate)`	Returns whether all elements of this stream match the provided predicate.
`boolean`	Stream.`anyMatch(Predicate<? super T> predicate)`	Returns whether any elements of this stream match the provided predicate.
`default Stream<T>`	Stream.`dropWhile(Predicate<? super T> predicate)`	Returns, if this stream is ordered, a stream consisting of the remaining elements of this stream after dropping the longest prefix of elements that match the given predicate.
`Stream<T>`	Stream.`filter(Predicate<? super T> predicate)`	Returns a stream consisting of the elements of this stream that match the given predicate.
`static <T,A,R> Collector<T,?,R>`	Collectors.`filtering(Predicate<? super T> predicate, Collector<? super T,A,R> downstream)`	Adapts a `Collector` to one accepting elements of the same type `T` by applying the predicate to each input element and only accumulating if the predicate returns `true`.
`static <T> Stream<T>`	Stream.`iterate(T seed, Predicate<? super T> hasNext, UnaryOperator<T> next)`	Returns a sequential ordered `Stream` produced by iterative application of the given `next` function to an initial element, conditioned on satisfying the given `hasNext` predicate.
`boolean`	Stream.`noneMatch(Predicate<? super T> predicate)`	Returns whether no elements of this stream match the provided predicate.
`static <T> Collector<T,?,Map<Boolean,List<T>>>`	Collectors.`partitioningBy(Predicate<? super T> predicate)`	Returns a `Collector` which partitions the input elements according to a `Predicate`, and organizes them into a `Map<Boolean, List<T>>`.
`static <T,D,A> Collector<T,?,Map<Boolean,D>>`	Collectors.`partitioningBy(Predicate<? super T> predicate, Collector<? super T,A,D> downstream)`	Returns a `Collector` which partitions the input elements according to a `Predicate`, reduces the values in each partition according to another `Collector`, and organizes them into a `Map<Boolean, D>` whose values are the result of the downstream reduction.
`default Stream<T>`	Stream.`takeWhile(Predicate<? super T> predicate)`	Returns, if this stream is ordered, a stream consisting of the longest prefix of elements taken from this stream that match the given predicate.
