MVC & String

[aNGaJe]

Hello all;
first of all i've created an Applet like;

import java.applet.*;
import java.awt.*;  
import java.awt.event.*;
 
public class uc extends Applet
implements ActionListener, MouseListener {
int x[]=new int[3], y[]=new int[3], turn = 0;
boolean reset;
 
public void init () {      
     addMouseListener (this);
     }
 
public void paint (Graphics g) {
     if (reset) {
          g.setColor (Color.white);
          g.fillRect (0,0,getSize().width,getSize().height);
          reset = false;
          g.setColor (Color.black);
     }
     else {
          if (turn>0)
          g.drawOval (x[turn-1], y[turn-1],1,1);
          if (turn==3) {
                triangle (g,x[0],y[0],x[1],y[1],x[2],y[2]);
                turn = 0;
          }
     }
}
 
public void triangle (Graphics g, int x1, int y1,
     int x2, int y2, int x3, int y3) {
     g.drawLine (x1, y1, x2, y2);
     g.drawLine (x2, y2, x3, y3);
     g.drawLine (x3, y3, x1, y1);
}
 
public void mouseClicked (MouseEvent evt) {
     x[turn] = evt.getX();
     y[turn] = evt.getY();
     turn++;
     update(getGraphics());
}
 
 
public void mousePressed (MouseEvent evt) {}
public void mouseReleased (MouseEvent evt) {}
public void mouseEntered (MouseEvent evt) {}
public void mouseExited (MouseEvent evt) {}
 
public void update(Graphics g) {
     paint (g);
}
 
public void actionPerformed (ActionEvent ae) {
     turn = 0;
     reset = true;
     update(getGraphics());
}
}

and after that teacher asked to make it using by Model View Controller & String; as like a beginer i cant start to work on it because i didnt understand how to start. Can anyone help about it ?
Best regards..

any idea?

First create classes that have no GUI code in them, but that contain the logic behind your current application. Write it in such a way that these classes could be used in a GUI or a console application. Note that you've got some program logic in your paint method where you reset turn, something that should never be done. The paint method (or paintComponent for Swing applications) should be for painting only and should contain no program logic.

You don't seem to be responding, but I'll give you the benefit of the doubt and post your current code and question here:

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import java.awt.geom.*;
 
public class TriangleComponent extends JComponent
{   private int[] positionX;
    private int[] positionY;
    private int clicks; 
    public TriangleComponent()
    { JFrame f=new JFrame();
        f.getContentPane().add(this);
       f.setSize(640, 480);
      f.setVisible(true);
      clicks = 0;
      MouseListener listener = new MouseTriListener();
      addMouseListener(listener);
      positionX = new int[3];
      positionY = new int[3];
    }
 
    public void paintComponent(Graphics g)
    {
        Graphics2D g2 = (Graphics2D) g;
        Point2D.Double r1 = new Point2D.Double(positionX[0], positionY[0]);
        Point2D.Double r2 = new Point2D.Double(positionX[1], positionY[1]);
        Point2D.Double r3 = new Point2D.Double(positionX[2], positionY[2]);
 
        Line2D.Double post1 = new Line2D.Double(r1, r2);
        Line2D.Double post2 = new Line2D.Double(r2, r3);
        Line2D.Double post3 = new Line2D.Double(r3, r1);
 
        g2.draw(post1);
        g2.draw(post2);
        g2.draw(post3);
    }
 
        class MouseTriListener implements MouseListener
        {
            public void mousePressed (MouseEvent event)
            {
                positionX[clicks] = event.getX();
                positionY[clicks] = event.getY();
                clicks++;
                if (clicks % 3 ==0)
                {
                    repaint();
                    clicks = 0;
                }
            }
 
            public void mouseReleased(MouseEvent event) {}
            public void mouseClicked(MouseEvent event) {}
            public void mouseEntered(MouseEvent event) {}
            public void mouseExited(MouseEvent event) {}
        }
          public static void main(String[] args)
            {
             new TriangleComponent();
            }
 
 
}

what do you think about now ? is it inclulding MVC ? used String as like noth. but.. idk
Best Regards.

With regards to your question, as far as I understand it, to be MVC compliant, your program must have more than one class, at least one being for the view, at least one for control and at least one for model. You need to break things down.
