Telephone Word Generator: 1. Write a program that, given a seven-digit phone num

Question

Telephone Word Generator:

1. Write a program that, given a seven-digit phone number, uses a PrintStream object to write to a

file every possible seven-letter word combination corresponding to that number. Avoid using

digits 0 and 1 in the phone number. There should be >2000 combinations for each phone

number.

2. Check each combination against any list of common English words, then output to a file only the

combinations that include a English word of at least 6 characters (such as FLOWERS), or include

exactly two English words (TOBEACH). You can find many such word lists available on Internet,

such as http://www.curlewcommunications.co.uk/wordlist.html.

I have attempted to write this program with a friends help and have comeup with the current code:

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

public class Phone extends JFrame
{
private int phoneNumber[];
private JTextField input;
private JLabel prompt;
public Phone()
{
super( "Phone" );
input = new JTextField( 15 );
input.addActionListener(

new ActionListener() { // anonymous inner class

public void actionPerformed( ActionEvent event )
{
calculate(); // calculate character sequences
}

} // end anonymous inner class

); // end call to addActionListener

prompt = new JLabel(
"Enter phone number (digits greater than 1 only):" );

Container container = getContentPane();
container.setLayout( new FlowLayout() );
container.add( prompt );
container.add( input );

setSize( 300, 100 );
setVisible( true );
}

// output letter combinations to file
private void calculate()
{
String letters[][] = { { "" },
{ "" }, { "A", "B", "C" }, { "D", "E", "F" },
{ "G", "H", "I" }, { "J", "K", "L" }, { "M", "N", "O" },
{ "P", "R", "S" }, { "T", "U", "V" }, { "W", "X", "Y" } };

long phoneNumber = Long.parseLong( input.getText() );
int digits[] = new int[ 7 ];
for ( int i = 0; i < 7; i++ ) {
digits[i] = ( int )(phoneNumber % 10);
phoneNumber /= 10;
}

PrintStream output = null;

try {
output = new PrintStream( new FileOutputStream( "phone.dat" ) );
}

catch( IOException exception ) {
JOptionPane.showMessageDialog( null, exception.toString(),
"Exception", JOptionPane.ERROR_MESSAGE );
System.exit( 1 );
}

input.setText( "Please wait..." );

int loop[] = new int[ 7 ];

// output all possible combinations
for ( loop[ 0 ] = 0; loop[ 0 ] <= 2; loop[ 0 ]++ )
for ( loop[ 1 ] = 0; loop[ 1 ] <= 2; loop[ 1 ]++ )
for ( loop[ 2 ] = 0; loop[ 2 ] <= 2; loop[ 2 ]++ )
for ( loop[ 3 ] = 0; loop[ 3 ] <= 2; loop[ 3 ]++ )
for ( loop[ 4 ] = 0; loop[ 4 ] <= 2; loop[ 4 ]++ )
for ( loop[ 5 ] = 0; loop[ 5 ] <= 2; loop[ 5 ]++ )
for ( loop[ 6 ] = 0; loop[ 6 ] <= 2; loop[6]++ ) {
for ( int i = 6; i >= 0; i-- )
output.print(
letters[ digits[ i ] ][ loop[ i ] ] );

output.println();
}

input.setText( "Done" );

output.close(); // close output stream

} // end method actionPerformed

public static void main( String args[] )
{
Phone application = new Phone();
application.setDefaultCloseOperation( JFrame.EXIT_ON_CLOSE );

Every time i try to compile i get an error saying: Phone.java:96: error: reached end of file while parsing application.setDefaultCloseOperation( JFrame.EXIT_ON_CLOSE );^

1 error

i need help with either writing a new code or could someone please explain what i need to do to get my current code to work? thanks
