paintComponent(Graphics g);

[Josh King]

Ive been confused a litttle about the paintcomponent that i cant run it. i have the code below

package foon;
import javax.swing.*;
import java.awt.*;
public class Graphics extends JPanel{

	public void paintComponent(Graphics g){
		g.setColor(Color.red);
		g.fillRect(20,50,100,100);
	}
	}

i think that you can call on the methodyou self but i wanted to see the rectangle in a realtime GUI but obvisly i have no main method.
i just wanted to know how would i be able to run this small graphic???

add the component to a JFrame
show the frame
java will handle the painting

Welcome to the Ranch.

In future, while posting code, please UseCodeTags. I have added them for you this time. As you can see the code tags, make the code much more easier to read and understand.

Moving to a more suitable forum...

And make the paintComponent() method protected, rather than public. It ought not to be called from any of your code; you leave the JVM to call it. And lots of people seem to ask the same question.

Additionally, as far as possible don't name your own classes the same as a JDK class, and especially not a JDK class that you use in your code.

Your class extending JPanel should not be named Graphics.
