Thread: I have a problem to load a set of points(x, y)

Hi guys
I will be very appreciate if somebody could tell me what is wrong with my code? Namely I am trying to develop a simple applet that has button "Load" to load set of points specified by x,y coordinates from a file and display these point in applet window. I store these point as ListArray everything seems to working fine apart displaying these point in window as specified by its coordinates. Could anybody help me with this issue, thanks in advance and the code is a below:
P.s I only attached the part of the code, If anybody can only suggest to load these values on display it on screen

public class Project extends JApplet implements ActionListener {
	private JPanel contentPane;
	private JPanel buttonPane;
	private JButton load;
	private RectangleArea rectangleArea;
	private PointSet pointSet = new PointSet();
	private Point pTemp = null;
	private boolean showMax = false;
 
        //This is my code to load data from data.txt 
	public Project() {
		init();
 
		try {
            ArrayList<Integer> column1 = new ArrayList<Integer>();   // Defining an integer Array List
            ArrayList<Integer> column2 = new ArrayList<Integer>();   // Defining an integer Array List
 
            Scanner myfile = new Scanner(new FileReader("E:\\app\\data.txt")); // Reading file using Scanner
 
            while (myfile.hasNext()) {          // Read file content using a while loop
                column1.add(myfile.nextInt());      // Store the first integer into the first array list
                column2.add(myfile.nextInt());    // Store the next integer into the second array list
            }
                System.out.println("column 1 elements are:\n" + column1);  
                System.out.println("column 2 elements are:\n" + column2);
 
 
            myfile.close(); // close the file
 
		}catch (Exception e) {   
            e.printStackTrace(); 
		}
 
	}
 
	public void init() {
		enableEvents(AWTEvent.WINDOW_EVENT_MASK);
		contentPane = (JPanel) this.getContentPane();
		buttonPane = new JPanel();
		contentPane.setLayout(new BorderLayout());
		GridLayout buttonLayout = new GridLayout(0,9);
		buttonPane.setLayout(buttonLayout);
		buttonPane.setBorder(BorderFactory.createEmptyBorder(1, 1, 1, 1));
		random = new JButton("Load");
		load.addActionListener(this);
		load.setToolTipText("Display data");
		buttonPane.add(Box.createHorizontalStrut(10));
		buttonPane.add(new JLabel("",SwingConstants.CENTER));
		buttonPane.add(new JLabel("",SwingConstants.CENTER));
		buttonPane.add(load);	
 
		buttonPane.add(new JLabel("",SwingConstants.CENTER));
		buttonPane.setAlignmentX(CENTER_ALIGNMENT);
		rectangleArea = new RectangleArea(this);
		MouseListener listener = new MouseListener(this);
		rectangleArea.addMouseListener(listener);
		rectangleArea.setAlignmentX(LEFT_ALIGNMENT);
		contentPane.add(rectangleArea,BorderLayout.CENTER);
		contentPane.add(buttonPane,BorderLayout.SOUTH);
	}
 
	public void actionPerformed(ActionEvent e){
		 if (e.getSource() == load) {
				//isOK=true;
				pointSet.clear();
		    //[B]I can set a single point
                    //But how to load these values from my txt fille [/B]		 
	            Point p = new Point();
				p.setX(44);
				p.setY(22);
				pointSet.addPoint(p);
				this.addPoint(p);
				this.setPTemp(p);
		 }
		 getRectangleArea().repaint();
		 }
 
	public void addPoint(Point p) {
		this.pointSet.addPoint(p);
	}
 
	public PointSet getPointSet() {
		return pointSet;
	}
 
	public void setPointSet(PointSet pointSet) {
		this.pointSet = pointSet;
	}
 
	public JButton getMaxD() {
		return maxD;
	}
 
	public void setMaxD(JButton maxD) {
		this.maxD = maxD;
	}
 
	public boolean isShowMax() {
		return showMax;
	}
 
	public void setShowMax(boolean showMax) {
		this.showMax = showMax;
	}
 
	public Point getPTemp() {
		return pTemp;
	}
 
	public void setPTemp(Point temp) {
		pTemp = temp;
	}
 
 
	public RectangleArea getRectangleArea() {
		return rectangleArea;
	}
 
	public void setRectangleArea(RectangleArea rectangleArea) {
		this.rectangleArea = rectangleArea;
	}
}

What's wrong with my post? I wasn't wrong about the MouseListener, the fact that there is no setX() or setY() in the Point class, or, as far as I know, that \ is an escape character.

Also, does the OP want the values of the points to be displayed on the screen or the points themselves, or both?

I mean, does he/she want:

ex.
1.) Point 1: x = 100 y = 200
Point 2 : x = 900 y = 500
........

or

2.) Do they want a point drawn on the screen? I can't find a drawPoints() method in the Graphics class and wouldn't know what to say as to how to do that.

Perhaps the Graphics drawOval() method with a height and width of like 1 or 2 or something like that.

The OP wasn't that clear as to what problem they were having with the displaying of the points.

1.) That they didn't know how to do it and were wondering how to
2.) That they tried something but it wasn't working.

Thank you for all the replies, but finally I managed to find a way to draw my points on JPanel. I didn't know how to load my points from my both ArrayList as a point's coordinates (x,y) and draw them on JPanel. I have all the classes but I was stuck with getting the x from one column1 and then y from column2 and to put them on the screen. Thank you again
