I am a student, and need a little direction. My instructior wants us to use the Swing Method to create a Word Counter in java.

I have it all written out, and it compiles. But the program will not go past the CMD.exe screen. It just hangs there. Any help would be appreciated.

Thanks.

Here is the Code.

PHP Code:

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


public class WordCounter extends JFrame implements ActionListener
{
    JPanel panel = new JPanel();
    JPanel button = new JPanel();
    JTextArea main = new JTextArea();
    JTextField result = new JTextField(5);
    JButton countWords = new JButton("Count the Words");
    JLabel wordCount = new JLabel("Total Word Count= ");

    public static void main(String[] args) throws IOException
    {
        //declaring variables
        String str;
        int totalWords = 0;
        int whitespaceCount = 0;
        int length = 0;
        BufferedReader dataIn = new BufferedReader(new InputStreamReader (System.in));
        str = dataIn.readLine();

        //loop while input is valid
                 while( str.length() > 0)
                 {
                    //converting strings
                     length = str.length();

                     //counting spaces in a string
                      for (int i = 0; i < length; i++)
                      {
                            if (Character.isWhitespace(str.charAt(i)))
                            whitespaceCount++;
                      }

                        //removing spaces

                           totalWords =  length-whitespaceCount;
        }


        //setting layout
        WordCounter w = new WordCounter();
        w.setSize(400,400);
        w.setTitle("Word Count");
        w.setResizable(false);
        w.setVisible(true);
        w.setLocation(300,300);


    }//end of main method

    public WordCounter()
    {
        Container c = getContentPane();
        c.setLayout(new BorderLayout());
        panel.setLayout(new GridLayout());
        button.setLayout(new FlowLayout(FlowLayout.CENTER));

        //adding components to their panels
        panel.add(main);
        button.add(countWords);
        button.add(wordCount);
        button.add(result);

        //add panels to frame
        c.add(panel, BorderLayout.CENTER);
        c.add(button,BorderLayout.SOUTH);

        //add funtionality to button
        countWords.addActionListener(this);
    }

    public void actionPerformed(ActionEvent e)
    {
    }
}//end of program
