How to draw lines in Java

Question

I\'m wondering if there\'s a funciton in Java that can draw a line from the coordinates (x1, x2) to (y1, y2)?

What I want is to do something like this:

Answer 1

To give you some idea:

public void paint(Graphics g) {
   drawCoordinates(g);
}

private void drawCoordinates(Graphics g) {

  // get width & height here (w,h)

  // define grid width (dh, dv)

  for (int x = 0; i < w; i += dh) {
    g.drawLine(x, 0, x, h);
  }
  for (int y = 0; j < h; j += dv) {
      g.drawLine(0, y, w, y);
  }
}
