Documentation Contents |
The java.lang package provides classes that are fundamental to
the design of the JavaTM programming
language. The java.lang.refs and java.lang.reflect
packages provide, respectively, reference-object classes and APIs
for obtaining reflective information about classes.
The java.util.* packages provide support for the event
model, collections framework, date and time facilities, and contain
various utility classes. The java.util.zip and
java.util.jar packages provide support for ZIP file
format and Java Archive (JAR) file formats respectively, and
the java.util.prefs package implements the Preferences API.
