Application with GUI

Here is the program (not yet complete.) It is based on the previous example, so most of it should be understandable. Decide what belongs in the program then click on the button to see an anwser. Look at the picture as you decide in what order to add components.

import java.awt.*; 
import java.awt.event.*;
import javax.swing.*; 

public class FahrConvert 
{
  JLabel title     = new JLabel("Convert Fahrenheit to Celsius");
  JLabel inLabel   = new JLabel("Fahrenheit    ");
  JLabel outLabel  = new JLabel("Celsius ");

  JTextField inFahr =  
  JTextField outCel = new JTextField( 7 );

  int fahrTemp ;  // input  
  int celsTemp ;  // result 
  
  public FahrConvert()   // constructor 
  {  
     // choose the layout manager 
     getContentPane().setLayout( ) ; 

     inFahr.addActionListener( this );
     getContentPane().add(   ) ;
     getContentPane().add(   ) ;
     getContentPane().add( outLabel );   
     getContentPane().add( inFahr );   
     getContentPane().add( outCel );   
     outCel.setEditable( ) ;
     setDefaultCloseOperation( WindowConstants.EXIT_ON_CLOSE );   
  }

   . . . . . .  //

}

The GUI is nearly complete, but more work is needed:

There should be code to deal with the user's input.
The application needs to be called to process the data.
The result should be displayed.
