Create a double (floating-point) variable named “dayOnIo” and set it to
152853.5047 . That's how many seconds a day lasts on Jupiter's moon, Io. 3
Create a string named myName and set it to your name.
Display each of these values by sending a chat message to the player, using
me.chat( string msg ) . For example, to display your name, type this:
me.chat( "My name is " + myName);
State each message with a string (like "My name is " ) and the plus sign. Then
add your variable. Don't forget the semicolon at the end of each statement.
Finally, add lines to play a sound effect at your location, using the float values
you just declared:
Location loc = me.getLocation();
playSound(loc, SoundEffect.Type.GHAST_SCREAM, volume, pitch);
Save the file and then run the build.sh in the Simple directory. (Make sure to
stop your server if you've left it running; some operating systems will throw
errors if you try to install fresh jars while the server is still running.)

Stop and restart your server, then connect from the Minecraft client. Run
your new command, /simple , and marvel at the messages on your console (and
the sound effect!).
Once that works, try changing the values for volume and pitch . Crank volume
up to 1.0f for a terrifying scream. For pitch, try a very low value, like 0.1f for
more of a growl, and higher ( 10.0f ?) for a piercing shriek.
After you type the new value in the Java source code, don't forget to take

Io is pretty cool. It has more than 400 active volcanoes. See http://en.wikipedia.org/wiki/Io_(moon) .
