                                ========================




    This program illustrates the use of the JFileChooser to navigate through a directory.

I. Below is the program:

import javax.swing.JFileChooser;
import java.io.*;
import java.util.Scanner;

public class Main {
    
    public static void main(String[] args) {
        System.out.println("Input With The JFile Chooser");
        System.out.println("============================\n\n\n");
        
        System.out.println("Read a file and copy it, one word per line.");
        // form a file chooser object
        JFileChooser chooser = new JFileChooser();
        // get the input file
        File in = null;
        int status = chooser.showOpenDialog(null);
        if (status == JFileChooser.APPROVE_OPTION)
        {
            in = chooser.getSelectedFile();
            String name = in.getPath();
            System.out.println("You selected " + name);
        }    
        
        // form the output file
        System.out.println("Enter the name of the output file.");
        Scanner keyboard = new Scanner(System.in);
        String outName = keyboard.next();
        try
        {        
            FileWriter fWriter = new FileWriter(outName);
            PrintWriter out = new PrintWriter(fWriter);
            // copy the input file 
            Scanner inFile = new Scanner(in);
            while (inFile.hasNext())
            {
                 String current = inFile.next();
                 out.println(current);
            }
            out.close();
        }
        catch(IOException exception)
	{
	    System.out.println("Error processing file: "
	     	    + exception);
	}
        
    }
    
}
