Hi, how do I translate the following code(s) in UML?

void update() { if( currentState == MAIN_MENU ) {

drawMainMenu(); checkMenuButtonClicked();

...

} else if( currentState == IN_GAME ) {

}

drawCharacters();

drawInterface();

getCurrentMove();

}

}

---------------------------------------------------------------------------

abstract class State { protected Game game; abstract void handleUpdate(); State(Game g) { game = g; }

}

class CharSelect extends State {

void handleUpdate() {

if selectedChar()

return new InGame(

 ..., selectedChar()); 

}

}

------------------------------------------

class Working {

ProcessState update() {

if( stuffToProcess() )

processStuff();

return new Working();

else

return new Waiting();

}

}
