Classpath of JAVA

Hello,
ABC question as I could not get a direct answer: How to locate the default IO class of JAVA? My question was triggered by the row in most java program
Code:
import java.io.*

as I am very curious where the io class is located in my Mint14 (Ubuntu12.10). I am aware it is similar to use DBI in PERL, or #include <stream> in C++, where I could locate the packages/libraries in certain directories:
Code:
/usr/lib/perl5/DBI.pm
/usr/include/c++/4.7/iostream

but I could not locate any file name (io.class, or io.jre) for this io class in java? Have checked my system for the libraries:
Code:
/usr/lib/jvm/java-7-openjdk-amd64/lib/
/usr/lib/jvm/java-7-openjdk-common/jre/lib/
/home/kevin/downloadsoftware/jre1.7.0_10/lib/
/usr/lib/eclipse/plugins/

Also checked Oracle website, where there is:
Code:
package java.io

but I could not find this file in my system, and the java program works fine. Can anybody give me some explanantion about the "default IO, file, string, date & time, etc classes" of java1.7.x when it was installed. My java is:
Code:
$java -version
java version "1.7.0_09"
OpenJDK Runtime Environment (IcedTea7 2.3.3) (7u9-2.3.3-0ubuntu1~12.10.1)
OpenJDK 64-Bit Server VM (build 23.2-b09, mixed mode)

Thanks a lot!

NAME
rmiregistry - Java remote object registry SYNOPSIS
rmiregistry [ port ] DESCRIPTION
The rmiregistry command creates and starts a remote object registry on the specified port on the current host. If port number is omitted, the registry is started on port 1099. The rmiregistry command produces no output and is typically run in the background. For example: example% rmiregistry & A remote object registry is a bootstrap naming service that is used by RMI servers on a host to bind remote objects to names. Clients can then look up remote objects and make remote method invocations. The registry is typically used to locate the first remote object on which an application needs to invoke methods. That object in turn pro- vides application-specific support for finding other objects. The methods of the java.rmi.registry.LocateRegistry class are used to get a registry operating on a particular host or host and port. The URL-based methods of the java.rmi.Naming class operate on a registry and can be used to look up a remote object, bind a simple (string) name to a remote object, rebind a new name to a remote object (overriding the old binding), unbind a remote object, and list the URLs bound in the registry. OPTIONS
The following option is supported: -Joption Used in conjunction with any java option, this option passes option (no spaces between -J and option) on to the java inter- preter. SEE ALSO
