Hand In: Printout of program code and dialogue of how it runs.
Purpose: Make an application that uses a Map structure
Description:
A good use of a map is to read in parameter-value pairs for a complex simulation.
For example, in a simulation of a building elevator system, the parameters to be loaded are:
numElevators
elevatorCapacity
numFloors
peoplePerHour
The datafile that is loaded has the parameter-value pairs separated by an equal sign, with one parameter-value pair
per line as follows:
numElevators=3
elevatorCapacity=6
numFloors=20
peoplePerHour=30
Make a program that reads in such a file, and builds a Map that relates the parameter name to it’s value. The
program should read in the file and then enter a loop where the user types in a parameter name and the program
gives it’s value. Make the parameter names case Insensitive. Remember, the object is to use a Map data structure,
so construct this program in such a way, even though you can do it with other structures.
