Description
Provides classes for performing arbitrary-precision integer arithmetic (
BigInteger) and arbitrary-precision decimal arithmetic (BigDecimal).Provides the classes and interfaces for the security framework.
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.
Utility classes commonly useful in concurrent programming.
