output shows null !!!!

[jawa]

hi all
can anyone tell me whats wrong with the code... the output gives only null rather than the supposed output

public class FDebugEight4
{
   public static void main(String[] args)
   {
      int x = 0, y;
      String[] array = new String[100];
      String entry;
      final String STOP = "XXX";
      StringBuffer message = new
          StringBuffer("The words in reverse order are\n");
     
      entry = JOptionPane.showInputDialog(null,		
        "Enter any word\n" +
        "Enter " + STOP + " when you want to stop"); 
      while(!(entry.equals(STOP))) 	//keep asking for word till XXX is inputed
		      {
         array[x] = entry;	
			x++;						
			entry = JOptionPane.showInputDialog(null,
            "Enter another word\n" +
            "Enter " + STOP + " when you want to stop"); 
				
      }
      for( y = x; y > 0 ; --y)
      {
         message.append(array[y]);
         message.append("\n");
      }
      JOptionPane.showMessageDialog(null, message);
   }
}

What line shows null and in what way?

Where does it say null?

When the user clicks the cancel button, you get a null. So all you have to do is to check to see if entry == null.

import javax.swing.JOptionPane;

public class FDebugEight4
{
   public static void main(String[] args)
   {
      int x = 0, y;
      String[] array = new String[100];
      String entry;
      final String STOP = "XXX";
      StringBuffer message = new
          StringBuffer("The words in reverse order are\n");
      
      entry = JOptionPane.showInputDialog(null,     
        "Enter any word\n" +
        "Enter " + STOP + " when you want to stop");
      while(entry != null && !(entry.equals(STOP)))  //keep asking for word till XXX is inputed
      {
         array[x] = entry;  
            x++;                        
            entry = JOptionPane.showInputDialog(null,
            "Enter another word\n" +
            "Enter " + STOP + " when you want to stop"); 
                 
      }
      for( y = x; y > 0 ; --y)
      {
         message.append(array[y]);
         message.append("\n");
      }
      JOptionPane.showMessageDialog(null, message);
   }
}
