Provides interfaces and classes for transferring data between and within
applications.
Provides for system input and output through data streams,
serialization and the file system.

performing I/O operations, such as files and sockets; defines selectors, for
multiplexed, non-blocking I/O operations.
Provides the API for accessing and processing data stored in a
data source (usually a relational database) using the
Java programming language.

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 principal classes and interfaces for the Java Print
Service API.
The scripting API consists of interfaces and classes that define
Java Scripting Engines and provides
a framework for their use in Java applications.
Provides the API for server side data source access and processing from
the Java programming language.

RowSet
implementations.Provides utility classes to allow serializable mappings between SQL types
and data types in the Java programming language.

use in its implementation of a synchronization provider.
Provides classes and interfaces that deal with editable and noneditable text
components.
Provides the class
HTMLEditorKit
and supporting classes for creating
HTML text editors.Provides the default HTML parser, along with support classes.
