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 this create new  class of paint and call it in main class

 package test;

import javax.swing.*;

import java.awt.*;

import java.awt.geom.Ellipse2D;

public class paint extends JComponent {

    public void paint(Graphics g)

    {

        Graphics2D g2 = (Graphics2D) g;

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

      

  Ellipse2D.Double E= new Ellipse2D.Double(4,10,100,149);

 g2.setColor(Color.LIGHT_GRAY);

 g2.fill(E);

  g2.draw(E);

  g2.setColor(Color.GREEN);

  Rectangle R= new Rectangle(24,74,20,20);

  g2.draw(R);

  g2.fill(R);

  R.translate(40, 0);

    g2.draw(R);

    g2.fill(R);

    g2.setColor(Color.orange);

    Rectangle R1= new Rectangle(52,94,3,23);

    g2.draw(R1);

    g2.fill(R1);

 Rectangle E2= new Rectangle(38,128,34,10);

g2.setColor(Color.red);

   g2.draw(E2);

   g2.fill(E2);

  

    }

   

}

Output is
