Packages that use Predicate

Package	Description
java.io	Provides for system input and output through data streams, serialization and the file system.
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.
