Program Plan Intro

To simulate a car sharing system

Program plan:

• In the file “Passenger.java”, import necessary packages, and create a class “Passenger”,
  • Declare necessary variables.
  • Define the constructor.
  • Define the method “getDestination()” to get the destination.
  • Define the method “toString()” to return the formatted string.
• In the file “Simulation.java”, import necessary packages, and create a class “Simulation”,
  • Declare Random object.
  • Define the constructor construct a simulation using a given generator.
  • Define the method “loadPassengers()” to pick up passengers from a station.
• In the file “Car.java”, import necessary packages, and create a class “Car”,
  • Declare necessary variables.
  • Define the constructor.
  • Define the accessor methods.
  • Define a method “drive()” to drive to the next station.
  • Define a method “dropOff()” to drop off any passengers who have arrived.
  • Define a method “add()” to add a passenger if there is room.
  • Define a method “toString()” to get the formatted string.
• In the file “Station.java”, import necessary packages, and create a class “Station”,
  • Create an ArrayList to hold people.
  • Define the constructor.
  • Define the method “getNumber()” to get the station number.
  • Define the method “add()” to add the passenger to the list.
  • Define the method “hasPeopleWaiting()” to know whether people are waiting.
  • Define the method “get()” to get the passenger at the given index.
  • Define the method “remove()” to remove the passenger at the specified index.
  • Define the method “peopleWaiting()” to know whether a person is waiting.
  • Define the method “toString()” to get the formatted string.
• In the file “SimulationTester.java”, import necessary packages, and create a class “SimulationTester”,
  • Define the method “main()”,
    • Create an object for “Simulation”, and “Station”.
    • Add the passenger Fred who is headed to 3.
    • Add the passenger Sally who is headed to 7.
    • Add the passenger Homer who is headed to 15.
    • Add the passenger Moe who is headed to 19.
    • Add the passenger Bart who is headed to 1.
    • Create an object for “Car”.
    • Call the method “loadPassengers()” to load the passengers at the station.
    • Print the actual and expected output.
    • Start at “10”, and go to “30”.
    • Call the method “loadPassengers()” to load the passengers at the station.
    • Print the actual and expected output.
    • Start at “10”, and go to “1”.
    • Call the method “loadPassengers()” to load the passengers at the station.
    • Print the actual and expected output.
