Overriding,Overloading methods

[Frank White]

I'm new to java, and I have a question. If I have the following:

CoolingSystem                   AirConditionar        HeatPump
fTargetTemp                     fACtemp               fHeatTemp
                --------------                 ------ 
Void cool(float)                void cool()           void cool(float)
Void heat(float)                void cool(float)      void heat(float)
                                     -                     -
                                     -                     -         
                                     -                     -        
                                     -                     -
                                     -----------------------
                                        Thermostat
                                        fRoomTemp
                                        void lowTemp(float)

I'm reading this book and i'm getting confused. Which is the overridding method(s) and overloading method(s), and what is the difference. How is this different from an overloaded constructer?

Thank you,
Moonjuice

In this scenario there is overridden methods. All are overloaded.

I'm confused by your diagram. This is similar to something described in Thinking in Java under the topic, Is-a vs. is-like-a relationships. Is this the example that you're working from? Or is there a more detailed version?
