finite state machines

hello,

Can anyone help me with drawing finite state machines in java please? an example would be very helpful. If I enter for example three states and also enter transitions between them for example state one goes to 3 and states 3 goes to states two. how would I draw this in java? does anyone have a good link or example document?

thanks
