To Do: We want a menu-driven program that keeps track of plant inventory for a nursery. I have a set of start files for you. Open up PlantDriver.java. This will be our beginning program. There are eight menu items that you need to get working (I did 0, 3 and 8). Run the program (it runs now but doesnt do anything except print and quit!). Your goal is to get the menu items to work. Note that the stub methods for the menu items are already written (they are in MenuInfo). Do not forget to implement Serializable for the blueprint classes. The code that I have written gives me an error message that says java.lang.NumberFormatException. Any assistance would be greatly appreciated!
