Hi,

public void actionPerformed(ActionEvent event)
    {
    	if(event.getSource()==room1 && event.getSource==breakfast)
    	{
    	    	// never reach this part of code
    	}
    	
    	
    }

the event is triggered only by one component, not by 2, in the same time, I don't know what you understand by "source from JButton and JCheckBox", but event.getSource() returns the object on which the event occurred, JButton or JCheckBox have no "source", they are sources for the event.

You probably need to get the selected state from the JCheckBox when a button is pressed. In that case:

public void actionPerformed(ActionEvent event)
    {
    	if(event.getSource()==room1) // if button room1 is pressed
    	{
    	    	boolean breakfastSelected = breakfast.isSelected(); // get state of check box
                // do more ...
    	}
    	
    	
    }
