   Sample(){
       //creating jpanel
               JPanel panel = new JPanel();
               frame = new JFrame("JFrame Example");
               panel.setLayout(null);
               //creating labels
               final JLabel label3 = new JLabel("Name: ");
               label3.setBounds(200, 15, 500, 30);
               JLabel label1 = new JLabel("Address: ");
               label1.setBounds(200, 50, 300, 30);

               final JTextField adult = new JTextField(10);
               adult.setBounds(400, 50, 100, 30);
               //creating labels
               JLabel label2 = new JLabel("Phone : ");
               label2.setBounds(200, 100, 250, 30);
               // password field
               final JTextField children = new JTextField(10);
               children.setBounds(400, 100, 100, 30);
               //adding to Jpanel
               panel.add(label1);
               panel.add(label2);
               panel.add(label3);
               panel.add(adult);
               panel.add(children);
               //adding JPanel to frame
               frame.add(panel);

               frame.setSize(600, 300);
               frame.setLocationRelativeTo(null);
               frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
               frame.setVisible(true);
   }
   public static void main(String s[]) {
           new Sample();
   }
}
