java.lang.Integer
Package
Description
Provides classes and interface relating to fonts.
Provides classes that are fundamental to the design of the Java
programming language.
Provides the classes for implementing networking applications.
Defines channels, which represent connections to entities that are capable of
performing I/O operations, such as files and sockets; defines selectors, for
multiplexed, non-blocking I/O operations.
Provides the API for accessing and processing data stored in a
data source (usually a relational database) using the
Java programming language.
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.
Service provider classes for the classes in the java.util package.
Classes to support functional-style operations on streams of elements, such
as map-reduce transformations on collections.
Public classes used by the built-in TIFF plug-ins.
Provides the core classes for the Java Management Extensions.
Provides the open data types and Open MBean descriptor classes.
Provides the definition of the Relation Service.
Interfaces for remote access to
JMX MBean servers.
The RMI connector is a connector for the JMX Remote API that
uses RMI to transmit client requests to a remote MBean server.
Provides the definition of the Timer MBean.
The scripting API consists of interfaces and classes that define
Java Scripting Engines and provides
a framework for their use in Java applications.
Provides a set of "lightweight" (all-Java language) components
that, to the maximum degree possible, work the same on all platforms.
Provides user interface objects built according to the Basic look and feel.
