Java TextField()

[tamkash]

Hi Guys,

I am just wondering how we show values in textField. I have created a random button which generates random number and prints number. I would like to show the random number in the textField whenever the button is pressed. Thanks.

import java.awt.*;
import java.applet.*;
import java.awt.event.*;
import java.util.Random;

public class Random2class extends Applet implements ActionListener {
   Button startButton;
   TextField textField;
   int[] anArray; 
   public void init()
   {
   //Flow Layout
   setLayout(new FlowLayout());
   startButton = new Button("Random");
   anArray = new int[10];
   textField = new TextField();
   add(startButton);
   add(textField);
   //Attach action to the components
   startButton.addActionListener(this);
   }
   
   public void actionPerformed(ActionEvent evt)
   {
	  if (evt.getSource() == startButton)
	  {   
		  Random random = new Random();
          int radiant = Math.abs(random.nextInt())%11;
          for (int i =0; i<1; i++)
          {   
        	  anArray[i]= radiant;
        	  String value = String.valueOf(anArray[i]);
        	  System.out.println(value);
        	     
          }
	  }
   }
}

textField.setText("I have been updated");
// do not update textField so quickly and frequently

for (int i=0; i<10; i++){
textField.setText(""+i);
}

If you update textField so frequently, you may see the textField blank and you can see the final value 9.
