Java Platform 1.2

Uses of Interface

Packages that use Comparable Provides for system input and output through data streams, serialization and the file system. 
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.sql Provides the JDBC package. 
java.text Provides classes and interfaces for handling text, dates, numbers, and messages in a manner independent of natural languages. 
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).
