Taking values from a text file inside paintcomponent

[sunny Kapadia]

Hi,

I want to read values from a text files from specified fields and use them as values to fill my methods inside the paintComponent() method. I am using for loop to do that but not able to do it properly. Can somebody give me a good example code howto do it ??
Here is extract of my code below:-

public class testing extends JPanel{
    private ArrayList<Myclass> lines;
    private HashMap<String,Color>  hm = new HashMap<String,Color>();
    private int firstvalue;
    private int width;
    private String color;
    private int f[];
     
    
   public void drawrects() {
         String n = null;  
    try{
            BufferedReader fh = new BufferedReader(new FileReader("myinput.txt"));	
            while(true){
               n = fh.readLine();
               if(n == null){
                  break;
               }else{
                  String f[] = n.split("\t");
                        int firstvalue = Integer.parseInt(f[3]);
                        int width = Integer.parseInt(f[4]); 
                        Color color = (Color)hm.get(f[7]);
                        Myclass lineinformation = new Myclass(color);
                        Myclass lineinformation = new Myclass(color);
                        lines.add(lineinformation);
 
   }       
          }
          fh.close();
       } catch (FileNotFoundException e) {
            e.printStackTrace();
        } catch (IOException e2) {
            e2.printStackTrace();
         }  
     } 
 public void paintComponent(Graphics g) {
    super.paintComponent(g);
    Graphics2D g2d = (Graphics2D) g;
     g2d.setRenderingHint(RenderingHints.KEY_ANTIALIASING,  
              RenderingHints.VALUE_ANTIALIAS_ON);  
    Myclass myobject = new Myclass();
    int x = myobject.firstvalue;
    int y = 60;
    int w = myobject.width;
    int z = 27;
    g2d.setRenderingHint( RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON);
    for(int i=0; i<Myclass.f.length; i++){
    GradientPaint gpi = new GradientPaint(0, 0, lines.get(i).getColor(), 0, 20, Color.white, true);
    g2d.drawRect(x, 60, w, 27);
    g2d.setColor(gpi);
    g2d.fillRect(x, 60, w, 27);
        
                                      }
 }
    

Thanks
