First it asks the user to input a number to select a certain type of fish. Each case takes user input and does something like this for whichever fish they selected: I_a fish1 = new fishtype();
I_a is the name of the constructor so that should already be defined in the other files. But just in general, say someone is using a constructor with the same variable for every selection in a switch statement, what do you do when it says the variable is already defined? It does not say that for the first choice, only every other one

Thanks
