java.util.function.Predicate
-
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.stream
Methods in java.util.stream with parameters of type Predicate Modifier and Type Method Description booleanStream. allMatch(Predicate<? super T> predicate)Returns whether all elements of this stream match the provided predicate.booleanStream. 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 aCollectorto one accepting elements of the same typeTby applying the predicate to each input element and only accumulating if the predicate returnstrue.static <T> Stream<T>Stream. iterate(T seed, Predicate<? super T> hasNext, UnaryOperator<T> next)Returns a sequential orderedStreamproduced by iterative application of the givennextfunction to an initial element, conditioned on satisfying the givenhasNextpredicate.booleanStream. 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 aCollectorwhich partitions the input elements according to aPredicate, and organizes them into aMap<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 aCollectorwhich partitions the input elements according to aPredicate, reduces the values in each partition according to anotherCollector, and organizes them into aMap<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.
