list The Java Class Library?
Java holds an extensive library of pre-written classes you can use in your programs. These classes are separated into groups known as packages. The Java 1.1 packages• java.applet • java.awt • java.awt.datatransfer • java.awt.event • java.awt.image • java.awt.peer • java.beans • java.io • java.lang • java.lang.reflect • java.math • java.net • java.rmi • java.rmi.dgc • java.rmi.registry • java.rmi.server • java.security • java.security.acl • java.security.interfaces • java.sql • java.text • java.util • java.util.zip
Each package describes a number of classes, interfaces, exceptions, and errors.
Packages can be split into sub-packages. for instance, the java.lang package has a sub-package known as java.lang.reflect. These are really fully different packages. A class in a sub-package has no more access to a class within the parent package (or vice versa) than it would to a class in a fully different package.
