How to add JLabel at run time in Swing?

I am making am window application on Java. I want to add label name at run time in my Swing application. How can I do this using Java Swing?

public class Component1 extends JPanel {

   Component1() {
      JLabel label = new JLabel("dd");
      label.setBounds(370, 340, 150, 20);
     // label.setText("labeVVl");
      add(label);
}

 public static void main(String[] args)
 {
    // create frame
    JFrame frame = new JFrame();
    final int FRAME_WIDTH = 800;
    final int FRAME_HEIGHT = 600;
    // set frame attributes
    frame.setSize(FRAME_WIDTH, FRAME_HEIGHT);
    frame.setTitle("My Frame");
    frame.setVisible(true);
    Component1 Com = new Component1();
    Component add = frame.add(Com);
}
}
