CSC1110 - Week 8 Homework

Overview

You will write a program that mimics the operations of the inside of an elevator. More specifically, the program simulates what happens when the user chooses to go to a particular floor, and it simulates what happens when the user pulls the elevator’s fire alarm. Assume the elevator is in a high-rise building that has floors numbered 1 through 100.

Instructions

Create an IntelliJ project using the GitHub link provided by your professor.

The repo will contain starter code for the Elevator and ElevatorDriver classes. Complete both of the classes based on the following specifications:

Elevator

Within your Elevator class, include these methods:

• selectFloor ─ This method takes your Scanner as a parameter and prompts the user for a floor selection, then performs input validation for the floor selection. If the floor selection is inappropriate (less than 1, greater than 100), then the method prints an error message. If the floor selection is OK, the method simulates going to that floor. See the sample session below for the format of the simulation message.
• fireAlarm ─ This method prints a “danger” message and then simulates going to the first floor. Note that I’m assuming this is a high tech fire alarm that is programmed to force the elevator to go to the first floor! See the sample session below for the format of the “danger” message

Elevator Driver

Within your ElevatorDriver class, use a loop that continues until the user enters “q” for quit. See the sample session for details.

As you implement your solution, you should find that the selectFloor and fireAlarm methods contain some repeated coding logic. To avoid unnecessary redundancies in your code, have those methods call an appropriate helper method.

Optional extension: Some hotels cater to superstitious people by omitting the 13th floor. Modify your program so that there is no 13th floor.
