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!

set_color(1)                                                           fish                                                           set_color(1)

NAME
set_color - set_color - set the terminal color set_color - set the terminal color Synopsis set_color [-v --version] [-h --help] [-b --background COLOR] [COLOR] Description Change the foreground and/or background color of the terminal. COLOR is one of black, red, green, brown, yellow, blue, magenta, purple, cyan, white and normal. o -b, --background Set the background color o -c, --print-colors Prints a list of all valid color names o -h, --help Display help message and exit o -o, --bold Set bold or extra bright mode o -u, --underline Set underlined mode o -v, --version Display version and exit Calling set_color normal will set the terminal color to whatever is the default color of the terminal. Some terminals use the --bold escape sequence to switch to a brighter color set. On such terminals, set_color white will result in a grey font color, while set_color --bold white will result in a white font color. Not all terminal emulators support all these features. This is not a bug in set_color but a missing feature in the terminal emulator. set_color uses the terminfo database to look up how to change terminal colors on whatever terminal is in use. Some systems have old and incomplete terminfo databases, and may lack color information for terminals that support it. Download and install the latest version of ncurses and recompile fish against it in order to fix this issue. Version 1.23.1 Sun Jan 8 2012 set_color(1)
