Advanced Programming Assignment

Warning!

Adhere to the Code of Academic Integrity. You may discuss background issues and general strategies with others and seek help from course instructor, but the implementations that you submit must be your own. You are not allowed to work out the detailed coding and solutions with others, copy code from published/Internet sources or let others to do coding for you. If you feel that you cannot complete the assignment on you own, seek help from the course instructor.

1 Elevator Simulation

In this assignment, you are asked to implement Elevator Simulation tool. The implemented simulator must take into the account multiple elevator characteristics including designing GUI, controlling elevator movement and elevator doors motions alongside simulating time taken to pick-up and drop- off passengers and so on.

1.1 GUI Design

1.2 Control Panel

What to do when a button is pressed?

Indicate (both internally and visually) the button is in a clicked

state

Indicate (both internally and visually) the number of times the button has been pressed

Code Example

class controlPanel extends JPanel implements ActionListener {

public Jbutton[] floorButton;

public int[] floorIn;

public controlPanel() {...//create GUI }

public void actionPerformed(ActionEvent e)

{...//handle button pressing events }

} //end of controlPanel class

1.3 Elevator

A panel to draw the elevator area, including the horizontal lines be- tween floors and the elevator itself

One possible design of the elevator is a rectangle with a vertical line striking through from the middle. You are encouraged to come up with other designs. Keep in mind that in extension, you need to simulate the door opening and closing

The elevator moves along the mid-line of the elevator area and between the bottom and top floors

1.4 Paint the elevator area PaintComponent(Graphics g)

Obtain the geometric values of components, e.g., the size, width, height of the button/panel, using tgetSize() or getWidth() and getHight()

Clear the drawing canvas of the panel

Draw horizontal lines

Draw the elevator

Hint: DO NOT use absolute coordinates to draw It cannot be resized!

1.5 Elevator moving is controlled by a Timer

The javax.swing.Timer class is a source component that automatically fires ActionEvents at a predefined rate.

Hint: The Timer class can be used to control animations. For ex- ample, you can use it to display a moving message.

Code Example

public class AnimationDemo extends JFrame {

public AnimationDemo() {

// Create a MovingMessagePanel for displaying a moving message

MovingMessagePanel p = new MovingMessagePanel("message moving?");

getContentPane().add(p);

// Create a timer for the listener p

Timer timer = new Timer(100, p);

timer.start();

}

public static void main(String[] args) {

AnimationDemo frame = new AnimationDemo();

...

} }

class MovingMessagePanel extends JPanel implements ActionListener {

private String message = "Welcome to Java";

private int xCoordinate = 5; private int yCoordinate = 20;

//to be continued...

public MovingMessagePanel(String message) {

this.message = message;

}

/** Handle ActionEvent */

public void actionPerformed(ActionEvent e) {

repaint(); }

/** Paint message */

public void paintComponent(Graphics g) {

super.paintComponent(g);

if (xCoordinate > getWidth()) xCoordinate = -100;

xCoordinate += 2;

g.drawString(message, xCoordinate, yCoordinate);

} }

1.6

Elevator moving is controlled by a Timer

actionPerformed(ActionEvent)

Adjust the Y coordinate of the elevator: decrease if the elevator

is moving up and increase if the elevator is moving down

Change the moving direction when the elevator reaches the top or bottom

Stop moving the elevator for a while if the elevator reaches a floor to pick up passengers; the stopping time is proportional to the number of passengers

Update the state: the elevator is moving up/down or picking up how many passengers at which floor

Update the button state: how many passengers are stilling waiting and if no, reset the button

Repaint the panel

1.7

1.8

Tips and Tricks

Interface, Interface, Interface! You will lose style points if you

simply copy the given interface example

Obtaining geometric values of components must be inside PaintCom- ponent(Gaphics g) method

If the elevator does not exactly stop on a floor (i.e., precisely placed on the floor horizontal line) by increasing or decreasing Y coordinate, force it if the gap is within a threshold

Not a good idea to set the moving interval to be 1 pixel only (although it does avoid this problem) because the elevator will move very slowly and you would expect problems adjusting its speed in Extension

Use the floorIn array in controlPanel to check whether a button has been pressed and if yes how many times when the elevator is passing by

Stop the elevator for 2 seconds

To make the elevator stop for a while, there are several ways, e.g., stopping the timer. A simple way is to do nothing for a few rounds in actionPerformed (ActionEvent e) when the Timer fires events. For example, if the Timer delay is 100 ms and actionPerformed executes nothing for 20 times, the elevator will stop for 100x20 = 2 seconds.

Code Example

//Handle the timer events

public void actionPerformed(ActionEvent e) {

if (stopping) {

if (looping++ == 20) {

stopping = false;

looping = 0; }

return; }

//to be continued...

if (up) { } //moving upwards

else { } //moving downwards

if (reaching a floor whose button is pressed) {

stopping = true;

}

}

2

The Extension (Bonus)

if (up) { } //moving upwards

else { } //moving downwards

if (reaching a floor whose button is pressed) {

stopping = true;

}

}

The extension task involves advanced functionality where it allows to specify destination floor internally and visually. Distention floor may be specified using where to go to dialog that lists all available floors but not current one. Furthermore, you must edit information panel to include the count of drop-out passengers.
