## Uses of Package
java.util

Packages that use java.util
java.awt |
java.io | Provides for system input and output through data streams, serialization and the file system.
java.lang | Provides classes that are fundamental to the design of the Java programming language.
java.math |
java.net | Provides the classes for implementing networking applications.
java.security | Provides the classes and interfaces for the security framework.
java.security.acl | The classes and interfaces in this package have been superseded by classes in the java.security package.
java.security.cert | Provides classes and interfaces for parsing and managing certificates.
java.text | Provides classes and interfaces for handling text, dates, numbers, and messages in a manner independent of natural languages.
java.text.resources |
java.util | Contains the collections framework, legacy collection classes, event model, date and time facilities, internationalization, and miscellaneous utility classes (a string tokenizer, a random-number generator, and a bit array).
java.util.jar | Provides classes for reading and writing the JAR (Java ARchive) file format, which is based on the standard ZIP file format with an optional manifest file.
java.util.zip | Provides classes for reading and writing the standard ZIP and GZIP file formats.

Classes in java.util used by java.util
AbstractCollection This class provides a skeletal implementation of the `Collection` interface, to minimize the effort required to implement this interface.
AbstractList This class provides a skeletal implementation of the `List` interface to minimize the effort required to implement this interface backed by a "random access" data store (such as an array).
AbstractMap This class provides a skeletal implementation of the `Map` interface, to minimize the effort required to implement this interface.
AbstractSequentialList This class provides a skeletal implementation of the `List` interface to minimize the effort required to implement this interface backed by a "sequential access" data store (such as a linked list).
AbstractSet This class provides a skeletal implementation of the `Set` interface to minimize the effort required to implement this interface.
BitSet This class implements a vector of bits that grows as needed.
Calendar `Calendar` is an abstract base class for converting between a `Date` object and a set of integer fields such as `YEAR`, `MONTH`, `DAY`, `HOUR`, and so on.

Enumeration An object that implements the Enumeration interface generates a series of elements, one at a time.
Hashtable This class implements a hashtable, which maps keys to values.
Iterator An iterator over a collection.
List An ordered collection (also known as a sequence).
