I'm new to java. I'm just looking for a little help with source code.

As a beginner i'm trying to write a code for CoolingSystem(s uper), fTargetTemp,voi d cool(float), void heat(float) is the top UML.

Then breaks down to two boxes...First subclass is AirConditioner, fACtemp,void cool(), voidcool(float) , and Second subclass is HeatPump, fHeatPump, void cool(float), void heat(float)...a nd finally it connects the two......
