important graphical user interface in java

This is main class

package test;

import java.awt.*;

import java.awt.geom.AffineTransform;

import java.awt.geom.Rectangle2D;

import java.awt.image.ColorModel;

import javax.swing.JFrame;

class Test

{

   public static void main(String args[])

         

   {  String title="ALLAH IS ONE";

       for(int i=0;i<3;i++){

       JFrame f= new JFrame();

       f.setSize(200,300);

       if(i==2)

       f.setTitle(title);

       paint P= new paint();

       f.add(P);

       f.setVisible(true);

      f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

 }

 }}

After the main class create a new class of paint and call it in main class

                  

package test;

import javax.swing.*;

import java.awt.*;

import java.awt.geom.Ellipse2D;

import java.awt.geom.Line2D;

public class paint extends JComponent {

    public void paint(Graphics g)

    {

        Graphics2D g2 = (Graphics2D) g;

        g2.drawString("An intelligent face", 10, 10);

       int i=1,j=1,k=1,l=1;

       for(int h=0;h<70;h++){

    Rectangle R= new Rectangle(i,j,k,l);

    g2.draw(R);

    i+=2;j+=2;k++;l++;

       }

}}

  

Output is
