fillRect method, can't call it properly

[kambar bek]

i m writing a java applet that accepts 4 parameters to draw a rectangle - x, y, width, height

my problem is, i don't know how to call it in another method - square of asterisks,

it needs a variable Graphics g to be supplied, but i don't know where to give this "g" variable!

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

public class ex_6_21 extends JApplet implements ActionListener{
	public void squareOfAsterisks(Graphics g, int x,int y, int width, int height){
		super.paint(g) ;
		g.fillRect(x,y,width,height) ;
	}

	JTextField x,y,width, height ;
	JTextArea outputArea ;
	
	public void init(){
		Container c = getContentPane() ;
		c.setLayout(new FlowLayout()) ;
		
		x = new JTextField(4) ;
		x.setEditable(true) ;
		c.add(x) ;
		
		y = new JTextField(4) ;
		y.setEditable(true) ;		
		c.add(y) ;
		
		width = new JTextField(4) ;
		width.setEditable(true) ;
		c.add(width) ;
		
		height = new JTextField(4) ;
		height.setEditable(true) ;
		height.addActionListener(this) ;
		c.add(height) ;
		
		outputArea = new JTextArea() ;
		outputArea.setText("") ;
		c.add(outputArea) ;
		
	}
	public void actionPerformed(ActionEvent e){
		
		int x_i = Integer.parseInt(x.getText()) ;
		int y_i = Integer.parseInt(y.getText()) ;
		int width_i = Integer.parseInt(width.getText()) ;
		int height_i = Integer.parseInt(height.getText()) ;
                Graphics g ;
		squareOfAsterisks( Graphics g,   x_i, y_i, width_i, height_i) ;
	}
}

here is the problem, how to initialize Graphics g variable?

                Graphics g ;
		squareOfAsterisks(Graphics g,   x_i, y_i, width_i, height_i) ;

By calling that method from an appropriate painting method override. Here's where to learn more about that: Performing Custom Painting
