A good answer might be:

  • How many AWT objects does the frame contain?
    • Four:
      • The Label "Enter Your Name:"
      • The TextField that follows it
      • The Label "Here is Your Name:"
      • The TextField that follows it.
  • Which of them need a registered listener?
    • Only the TextField that the user types into.

Repeater

The Labels do not need listeners because they generate no actions. The bottom TextField does not need a listener because it will have its text set by the program (this is not an event.) Here is the application. Decide what should go in place of the ten buttons: 

import java.awt.*; 
import java.awt.event.*;

public class Repeater extends Frame implements ActionListener
{


   Label inLabel     = new  (" " ) ;

   TextField inText  = new TextField( 15 );


   Label outLabel     = new  (" " ) ;

   TextField outText = new TextField( 15 );
   
   Repeater()                              // constructor
   {  
      setLayout( new FlowLayout() );        

      add(   ) ;


      add(   ) ;


      add(   ) ;


      add(   ) ;



      inText.addActionListener( ) ;

   }

  public void actionPerformed( ActionEvent evt)  
  {
    String name = inText.getText();

    outText.( name );

    repaint();                  
  }

  public static void main ( String[] args )
  {
    . . . . . .
  }
}

    . . . . . .

Click on a button to see what should go there. (This may not work on some web browsers. The text-only version of the program is in the next page.)

QUESTION 9:

How many of the ten blanks (buttons) did you get correct?
