    Default How to store objects from a class inn an array?

    Hey, im working on a program where i need to use the objects wich i get from the class "Borrehull" and store them inn an array.

    import java.io.Serializable;
     
     
    public class Borrehull implements Serializable{
     
    	private int x;
        private int y;
        private int d;
     
    	 public Borrehull (int xkoord,int ykoord,int dim){
    	    x=xkoord;
    	    y=ykoord;
    	    d=dim;
    	  }
     
    	  public int getx() {
    	    return x;
    	  }
     
    	  public int getd() {
    	    return d;
    	  }
     
    	  public int gety() {
    	    return y;
    	  }
    }

    i am using a mouse actionlistener in the "main" program where i get the x and y koordinates when i click on the frame and the dim can i adjust with some grouped radiobuttons, here is the part og the "main" program where i get the x and y koordinates with getX() and getY():

     
    class Tegne extends JPanel {//starts Tegne extends JPanel
     
    public Tegne() {//starts Tegne
     
     
    	//create a mouselistener
    	addMouseListener(new MouseListener(){
     
    		public void mouseClicked(MouseEvent arg0) {
    			if (arg0.getButton()==1)//mouse left button
    			{
     
    			y=arg0.getY();
    		             x=arg0.getX();
     
    			panel();
    			repaint();
    			}
    		}
     
    		public void mouseEntered(MouseEvent arg0){} 
    		public void mouseExited(MouseEvent arg0){} 
    		public void mousePressed(MouseEvent arg0){}	
    		public void mouseReleased(MouseEvent arg0){} 	
     
    	});
     
    }//ends Tegne	
     
    	protected void paintComponent(Graphics g){
     
    		super.paintComponent(g);			                           
    									g.setColor(Color.red);
    			if(x>0|y>0 & diameter>0)g.fillOval(x,y ,diameter*2 ,diameter*2);
    		}
     
    }//ends Tegne extends JPanel


    all help will be much appreciated(:

    Not exactly sure what you are asking, but I guess you want to know how to use arrays? This tutorial could maybe help (havent looked that much at it since I am in a hurry).
