Uses of Class
java.lang.Number

Packages that use Number
java.lang	Provides classes that are fundamental to the design of the Java programming language.
java.math	Provides classes for performing arbitrary-precision integer arithmetic (BigInteger) and arbitrary-precision decimal arithmetic (BigDecimal).
java.text	Provides classes and interfaces for handling text, dates, numbers, and messages in a manner independent of natural languages.
javax.accessibility	Defines a contract between user-interface components and an assistive technology that provides access to those components.
javax.swing	Provides a set of "lightweight" (all-Java language) components that, to the maximum degree possible, work the same on all platforms.
