Question

What the program is supposed to do
Print the squares of one through ten to a file whose name is typed in by the user.
My Program
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
import java.io.*;
public class SquareSend
     private JTextField field;
     public static void main(String[] args)
          SquareSend gui = new SquareSend();
          gui.go();
     public void go()
          JFrame frame = new JFrame();
          JTextField field = new JTextField();
          field.addActionListener(new sendToFile());
          frame.getContentPane().add(BorderLayout.CENTER, field);
          frame.setSize(300, 50);
          frame.setVisible(true);
     public class sendToFile implements ActionListener
          public void actionPerformed(ActionEvent e)
               FileOutputStream out;
             PrintStream p;
             try
                     out = new FileOutputStream(field.getText());
                     p = new PrintStream( out );
                     int x = 1;
                      while (x<11)
                           int y = (int)(Math.pow(x,2));
                           p.println("The square of "+x+" is "+y+".");
                           x++;                           
                     p.close();
             catch (Exception f)
                     System.err.println ("Error writing to file");
Error Message
Error writing to file (display message if designated in the try...catch statement).
Thanks for your help

Answer 1

use f.printStackTrace() in your catch clause if you want more information about the exception thrown.
