Assume that the GarageDoorSystem class in Figures 7.25a and 7.25b has another instance variable:

public final String SYSTEM_ID;

Rewrite the GarageDoorSystem constructor so that it calls a helper method called initialize which asks the user to supply a name for SYSTEM_ID. In that method, also ask the user if the starting position is to be up. Then, use the user’s input to initialize the state variable, assuming the only possible starting states are down (0) or up (2).
