drawing in a JPanel

i have my class declared:

public class myRightPanel extends JPanel

then i override the paintComponent of my super class like this:

public void paintComponent(Graphics g){  
        super.paintComponents(g);
                //Draw bunch of things here
}

Now it turns out i also need a method which takes in two integer(x,y) parameters and adds something to my already drawn myRightPanel at that coordinates. How do i do this when i have already overridden my paintComponent()?

Store the x,y as a Point as an attribute of the class so it is accessible within the paint method. Call repaint().

You need to use the Graphics object to draw any content you want.

For example:

public void paintComponent(Graphics g){  
  super.paintComponents(g);
  g.drawString("Hello test", 0, 0);
}

I recommend reading Java 2D tutorial: http://docs.oracle.com/javase/tutorial/2d/index.html
