How to embed string into rectangle?

Question

Hi all.
I have a rectangular area to draw the string, but the string can be wider than the rectangle it should fit. How to draw truncated string? For example:
public void paintComponent(Graphics g) {
          String s = new String("This is a very long string");
          int x = 0;
          int y = 0;
          int rectWidth = 20;
          int rectHeight = 10;
          Rectangle r = new Rectangle(x, y, rectWidth, rectHeight);
          int strWidth = g.getFontMetrics().stringWidth(s);
          if (strWidth > rectWidth) {
               System.err.println("How to do that?");
          } else {
               g.drawString(s, x, y);
     }Thank you in advance.

If what you want is for your clipped string to display the "..." just like JLabel does, here is an algorythm that you can use:
1- If the font metrics tells you that your string is going to get clipped, start removing chars from the end
2- add "..." to the shortened string.
3- if that string now fits, done
4- else goto 1
