Uses of Class
java.lang.Number
Package
Description
Contains all of the classes for creating user interfaces and for painting
graphics and images.
Provides classes that are fundamental to the design of the Java
programming language.
Provides classes for performing arbitrary-precision integer
arithmetic (
BigInteger
) and arbitrary-precision decimal
arithmetic (BigDecimal
).Provides classes and interfaces for handling text, dates, numbers,
and messages in a manner independent of natural languages.
A small toolkit of classes that support lock-free thread-safe
programming on single variables.
Defines a contract between user-interface components and an assistive
technology that provides access to those components.
Provides the core classes for the Java Management Extensions.
Provides the definition of the monitor classes.
Provides a set of "lightweight" (all-Java language) components
that, to the maximum degree possible, work the same on all platforms.
Defines XML/Java Type Mappings.
