Hi Friend,

Try the following code:

import java.io.*;
import java.util.*;
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.filechooser.*;
public class CountWordsFromFile extends JFrame {

JButton button;
JPanel p;
JLabel l1,l2,l3;
String dirName = "C:\\Answers\\ImagesAndText\\";
int count=0;

CountWordsFromFile(){
p=new JPanel(new GridLayout(4,1));
l1=new JLabel();
l2=new JLabel();
l3=new JLabel();
button=new JButton("Get File Details");
p.add(l1);
p.add(l2);
p.add(l3);
p.add(button);

l1.setVisible(false);
l2.setVisible(false);
l3.setVisible(false);
add(p);
setVisible(true);
pack();
button.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent e){
JFileChooser chooser = new JFileChooser();
chooser.setCurrentDirectory(new File(dirName));
chooser.setFileSelectionMode(JFileChooser.FILES_ONLY);

FileNameExtensionFilter filter = new FileNameExtensionFilter(
".txt and .java files", "txt", "java");
chooser.setFileFilter(filter);

try {
int code = chooser.showOpenDialog(null);
if (code == JFileChooser.APPROVE_OPTION) {
File selectedFile = chooser.getSelectedFile();
Scanner input = new Scanner(selectedFile);
while (input.hasNext()) {
++count;
input.next();
}
String f=selectedFile.getName();
long size=selectedFile.length();
l1.setText("File Name is: "+f);
l2.setText("File Size is: "+Long.toString(size));
l3.setText("No of words : "+Integer.toString(count));
l1.setVisible(true);
l2.setVisible(true);
l3.setVisible(true);

}

} catch (Exception f) {
f.printStackTrace();
}
}
});
}
public static void main(String[] a) {
CountWordsFromFile c=new CountWordsFromFile();
}
}

Thanks
