Uses of Class
java.math.BigDecimal
Package
Description
Provides classes for performing arbitrary-precision integer
arithmetic (
BigInteger
) and arbitrary-precision decimal
arithmetic (BigDecimal
).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.
Provides the open data types and Open MBean descriptor classes.
Provides the API for server side data source access and processing from
the Java programming language.
Standard interfaces and base classes for JDBC
RowSet
implementations.Provides utility classes to allow serializable mappings between SQL types
and data types in the Java programming language.
Defines XML/Java Type Mappings.
