I forget java but in VB.NET

OfficeAC is a type of AirConditioner.

Dim OfficeAC as new AirConditioner()

Turn on Air

OfficeAC.turnOn()

Set Temp

OfficeAC.setTemp(69)

Turn Off

OfficeAC.turnOff()

Destroy it ala Office Space Style

OfficeAC = Nothing

It should look similar in java. It's not that hard really.
