Java Packages

Java interfaces and classes are grouped into packages. The following lists the java packages, from which you can access interfaces and classes.

java.lang
Package that contains essential Java classes, including numerics, strings, objects, compiler, runtime, security and threads. Unlike other packages, java.lang is automatically imported into every Java program.
java.io
Package that provides a set of input and output streams to read and write data to files, strings, and other sources.
java.util
Package containing miscellaneous utility classes, including generic data structures, settable bits class, time, date, string manipulation, random number generation, system properties, notification, and enumeration of data structures.
java.net
Package for network support, including URLs, TCP sockets, UDP sockets, IP addresses and a binary-to-text converter.
java.awt
Package that provides user interface features such as windows, dialog boxes, buttons, checkboxes, lists, menus, scrollbars and text fields. (Abstract Window Toolkit)
java.awt.image
Package for managing image data, such as the setting the color model, cropping, color filtering, setting pixel values and grabbing snapshots.
java.awt.peer
Package that connects AWT components to their platform-specific implementation (such as Motif widgets or Microsoft Windows controls).
