paint and paintcomponent

[wired-in=p]

I am sort of confused about paint and paintcomponent. I set up a small program that will help me to understand.

import javax.swing.*;
import java.awt.*;

public class test extends JFrame
{
	public test()
	{
		super();
		add(new mypanel());
		setVisible(true);
		setDefaultCloseOperation(3);
		setSize(500, 500);
	}
	public static void main(String args[])
	{
		test test = new test();
	}
	public class mypanel extends JPanel
	{
		public void paint(Graphics g)
		{
			Graphics2D g2 = (Graphics2D)g;
			Rectangle rect = new Rectangle(50,50, 50, 50);
			GradientPaint paint = new GradientPaint(50, 50, Color.cyan, 100, 100, Color.red);
			g2.setPaint(paint);
			super.paint(g);
		}
		public void paintComponent(Graphics g)
		{
			Graphics2D g2 = (Graphics2D)g;
			Rectangle rect = new Rectangle(50,50, 50, 50);
			g2.draw(rect);
			g2.fill(rect);
		}
	}
}

Why doesn't the circle draw with the gradientpaint defined in the paint method?

The circle does draw but is erased by the super.paint(g) method which paints the default background for the JPanel over the previous drawings. Usually super.paint(g) is called first. This should all be done in paintComponent though, by the way.

when i take the super.paint(g) away it still wont paint the rectangle. and also when should the paint method be used?

It doesn't work if you call super.paint(g) at the beginning of paint and super.paintComponent(g) at the beginning of paintComponent?

..and also when should the paint method be used?

Usually never. You'll use it if you override painting of child components and borders, something that is a rare occurance.
