2 2 of 9 11/24/2003 4:24 PM This class represents a File Opener. It has two tasks: Open a file and read text from that Ryan Prins, Rufina Virata, Kunal Gunar (Project 2) Created on Nov 3, 2003 Last Updated on Nov 24, 2003 public class FileOpener chooser variable that will be used to open a folder private JFileChooser chooser; string representation of an abstract file path private String filepath; to read data in big chunks private BufferedReader br; used to get the file information private FileReader fr; varible to store the selected file private File infile; variable to store lines from the file while reading private String textline; This constructor creates new JFileChooser and new WordDictionary Objects and intializes instance IOException public FileOpener() throws IOException chooser = new JFileChooser(); This method opens JFileChooser to select files and returns file's path name. It also handles exceptions if they The path of the file that was selected by the IOException public String openfile() throws IOException try chooser.setdialogtitle("select a Maze Data File"); chooser.showopendialog(null); infile = chooser.getselectedfile(); this.filepath = infile.tostring(); this.fr = new FileReader(filePath); this.br = new BufferedReader(fr); catch(nullpointerexception e) // Run this if the user presses cancel chooser.cancelselection(); return filepath; This method read chars from a String line containing chars. After iteratining through each character in the line, a word is formed excluding the space character. Then this word is added in to the Will return the next line when the file path is not IOException public String readtext() throws IOException if (this.filepath!= null) this.textline = br.readline(); return this.textline;

3 3 of 9 11/24/2003 4:24 PM file2.java-tab =4 file2.java Launcher.java import java.awt.; import javax.swing.; import java.io.; This class will start our simulation and create the needed objects to start the simulat Ryan Prins, Rufino Virata Created November 24, 2003 public class Launcher Main method to get the simulation IOException public static void main(string[] args) throws IOException JFrame frame = new JFrame("My Maze demo"); frame.setdefaultcloseoperation(windowconstants.dispose_on_close); MazeDrawer yourmom = new MazeDrawer(500,500); frame.getcontentpane().add(yourmom); frame.pack(); frame.setvisible(true); MazeModel m = new MazeModel(); m.addview(yourmom); file3.java-tab =4 file3.java MazeDrawer.java import java.awt.; import javax.swing.; import java.util.; This class created the visual aspects of our project. This will present the user a window that will display the maze and the different aspects within Rufino Virata, Ryan Prins Created November 24, 2003 public class MazeDrawer extends JPanel Instance of our Model - MazeModel private MazeModel model = null;

4 4 of 9 11/24/2003 4:24 PM This constructor sets the size of the window that the user will h The height of the l The length/wideth of the window. public MazeDrawer(int h, int l) setpreferredsize(new Dimension(h,l)); This will notify the operating system that a repaint is m The model that will update viewer public void notify(mazemodel m) model = m; repaint(); This method will update the view and add the needed rectangles to the view depending on the data that was contained in the data file. From this the complete view will be made with the red squares being walls and the white squares being open for g The graphics unit that will be updated. public void paintcomponent(graphics g) //clear the view Rectangle bounds = getbounds(); g.setcolor(color.blue); g.fillrect(0,0, bounds.width, bounds.height); if(model!=null) int rowlength=bounds.width/model.getrows(); int columnlength=bounds.height/model.getcolumns(); int xbegin=0; // The beginning point of drawing for x int ybegin=0; // The beginning point of drawing for y final int INCREASE_IN_Y = columnlength; // The amont to increase the y value afte r each row for(int i=0;i<model.getrows();i++) for(int k=0; k<model.getcolumns();k++) if(model.isfilled(i,k)) g.setcolor(color.red); // If the block should be filled else g.setcolor(color.white); g.fillrect(xbegin,ybegin,rowlength,columnlength); xbegin+=rowlength; ybegin += INCREASE_IN_Y; xbegin=0; // If the block should not be filled file4.java-tab =4 file4.java MazeModel.java import java.util.; import java.io.; This class contains all of the data that makes up the model.

5 5 of 9 11/24/2003 4:24 PM This will ask the user for an input data file and then will take that data and store it in an Array (boolean). This data will be made available to the viewer so that a proper representation of the model can be made Ryan Prins, Rufino Virata Created November 24, 2003 public class MazeModel The boolean array that stores all of our box data on whether to fill in the box or n ot. private boolean[][] boxarray; An instance of our FileOpener class. private FileOpener fo; Used to break up the data when it is streamed in. private StringTokenizer st; An ArrayList of all the available viewers. private ArrayList viewers; An integer value that is used as a placeholder to create in int. private Integer inta; The number of rows that are in the model private int numrows; The number of columns that are in the model private int numcolumns; The current row. private int rows; The current column. private int columns; Main constructor that will create an instance of the FileOpener class and thus ask the user for a file to use for the data. This will then call various methods to populate the Array with IOException public MazeModel() throws IOException // create new instance of file reader class viewers = new ArrayList(); fo = new FileOpener(); fo.openfile(); String line = fo.readtext(); rows = 0; columns = 0; Integer inta=new Integer(0); st = new StringTokenizer(line); if(st.hasmoreelements()) rows = inta.parseint((st.nexttoken())); columns = inta.parseint((st.nexttoken())); this.numrows=rows; this.numcolumns=columns; boxarray = new boolean[rows][columns]; getfilled(); This constuctor is used for the prupose of JUnit testing. No input is allowed from the user for this r The number of c The number of columns public MazeModel (int r, int c) this.numrows=r; this.numcolumns=c; boxarray = new boolean[r][c];

6 6 of 9 11/24/2003 4:24 PM Will add the given Objet to the list of viewers and notify the v The object to be added to the list of viewers. public void addview(object v) viewers.add(v); ((MazeDrawer)v).notify(this); This class will take the input from the data file and then populate the array with values that will let the drawer know which boxes are the be filled or not. private void getfilled() throws IOException String line = fo.readtext(); while(line!=null) st = new StringTokenizer(line); if(st.hasmoreelements()) rows = inta.parseint((st.nexttoken())); columns = inta.parseint((st.nexttoken())); populatearray(rows, columns); line = fo.readtext(); The method will set an Array component to true when it is determined that this box will be row The row of the box to be column The column of the box to be filled. public void populatearray(int row, int column) boxarray[row][column] = true; Basic tostring method that will print out what the current contents of the specific Array paramater r The row that the user is interested c The column that the user is interested in. public void tostring(int r, int c) System.out.println(boxArray[r][c]); Will give the user the number of rows in the The number of rows in the Array. public int getrows() return this.numrows; Will give the user the number of columns in the The number of columns in the Array public int getcolumns() return this.numcolumns;

7 7 of 9 11/24/2003 4:24 PM Will let the user know whether or not if this cell is filled (true) or not r The row you are interested c The column that you are interested True if it is to be filled, False if otherwise. public boolean isfilled(int r, int c) return boxarray[r][c]; file5.java-tab =4 file5.java MazeModelTest.java import junit.framework.; import java.util.; import java.io.; Class to test our model and if it functions as we feel that it Ryan Prins, Rufino Virata Created November 24, 2003 public class MazeModelTest extends TestCase //instance variables Instance of our MazeModel class. Will be what is tested. public MazeModel model; Set up data for tests. public void setup() model = new MazeModel(10,10); model.populatearray(0,0); model.populatearray(1,1); model.populatearray(3,7); model.populatearray(4,8); model.populatearray(2,9); model.populatearray(1,4); Test to see if the isfilled method returns that we feel that it should. Should return True if we populated that cell in setup(), false otherwise. public void testisfilled() asserttrue(model.isfilled(0,0)); asserttrue(model.isfilled(1,1)); asserttrue(model.isfilled(3,7)); asserttrue(model.isfilled(4,8)); asserttrue(model.isfilled(2,9)); asserttrue(model.isfilled(1,4)); assertfalse(model.isfilled(2,2)); assertfalse(model.isfilled(4,4)); Check to see that the proper number of rows are returned.
