## Uses of Interface
java.util.Iterator

Packages that use Iterator
java.applet | Provides the classes necessary to create an applet and the classes an applet uses to communicate with its applet context.
java.awt.dnd | Drag and Drop is a direct manipulation gesture found in many Graphical User Interface systems that provides a mechanism to transfer information between two entities logically associated with presentation elements in the GUI.
java.beans.beancontext | Provides classes and interfaces relating to bean context.
java.nio.charset.spi | Service-provider classes for the ``java.nio.charset`` package.
java.security.cert | Provides classes and interfaces for parsing and managing certificates, certificate revocation lists (CRLs), and certification paths.
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).
javax.imageio | The main package of the Java Image I/O API.
javax.imageio.spi | A package of the Java Image I/O API containing the plug-in interfaces for readers, writers, transcoders, and streams, and a runtime registry.
