Hi

I'm trying to write a program that reads a line for that buffer than open that file. I have already written that program and it open up the file when I enter the directory but it will not open a file when I enter in a line form that file.
can someone please help!!!!

Here is an sample program to gave you an idea of what I'm doing:

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

import javax.swing.*;

public class TextFile2 extends JFrame implements ActionListener
{

private JTextField enterField;
private JTextArea outputArea;
private JLabel pathLabel;

public TextFile2()
{
super ("OPUS");

enterField = new JTextField("Enter file directory here");

enterField.addActionListener(this);
outputArea = new JTextArea();

ScrollPane scrollPane = new ScrollPane();
scrollPane.add( outputArea );

Container container = getContentPane();
container.add(enterField, BorderLayout.NORTH);
container.add(scrollPane, BorderLayout.CENTER);

setSize( 500, 500);
show();
}

public void actionPerformed (ActionEvent actionEvent )
{
File name = new File (actionEvent.getActionCommand() );

if (name.exists() )
{
outputArea.setText(
name.getName() + " exist\n" +
( name.isFile() ?
" is a file\n" : " is not a file\n" ) +
( name.isDirectory() ?
" is a directory\n" : " is not a directory\n" ) +
( name.isAbsolute() ?
" is absolute path\n" : " is not absolute path\n" ) +
"Last modified: " + name.lastModified() +
"\nPath: " + name.length() +
"\nAbsolute path: " + name.getAbsolutePath() +
"\nParent: " + name.getParent() );

if (name.isFile())
{
try
{
BufferedReader input = new BufferedReader(
new FileReader( name ));
StringBuffer buffer = new StringBuffer();
String text;
outputArea.append("\n\n" );

while ( (text = input.readLine()) != null )
buffer.append(text + "\n" );

outputArea.append ( buffer.toString() );
}

catch (IOException ioException )
{
JOptionPane.showMessageDialog( this,
"FILE ERROR",
"FILE ERROR", JOptionPane.ERROR_MESSAGE );
}
}

else if (name.isDirectory() )
{
String directory[] = name.list();

outputArea.append( "\n\nDirectory contents: \n");

for (int i = 0; i < directory.length; i++ )
outputArea.append( directory + "\n");
}
}

else
{
JOptionPane.showMessageDialog( this, actionEvent.getActionCommand() + "Does NOT Exist",
"ERROR", JOptionPane.ERROR_MESSAGE );
}
}

public static void main (String args[] )
{
TextFile2 application = new TextFile2();

application.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE );
}
}

It works as it is.
What is the problem?
I think I didn't get it.

(next time enclose the java code between the java tags)
