JAVA beginner: create a screen where i can write messages

[markafar]

Hi i am doing an assignment and came across a problem. basically i need to create a screen where i can write messages and save them to individual text files. i managed to create the screen but the messages are either being appended to the same text file or not being written at all, the code is here

try
{
for (int nextNumber = 0; nextNumber <99; nextNumber++ )
{
String directoryPath = "c:\\DATAX\\";
String filename = directoryPath + "\\msg" + nextNumber + ".txt";
File newFile1 = new File (filename);
try
{
if(!newFile1.exists())
{
newFile1.createNewFile();
break ;
}
}
catch (IOException e){
}
BufferedWriter out = new BufferedWriter(new FileWriter (filename));
//BufferedWriter out = new BufferedWriter(new FileWriter(filename,true));
messageWindow.write(out);
out.flush();
out.close();
}
}
catch (IOException e1)
{
e1.printStackTrace();
}
finally
{
JOptionPane.showMessageDialog(null, "Your Message has been successfully saved");
}

i need to always save the written message to a new text file. can someone help me pls?

thanks

Check the below code of the program example:

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

public class ShowDialogBox{
  JFrame frame;
  public static void main(String[] args){
  ShowDialogBox db = new ShowDialogBox();
  }

  public ShowDialogBox(){
  frame = new JFrame("Show Message Dialog");
  JButton button = new JButton("Click Me");
  button.addActionListener(new MyAction());
  frame.add(button);
  frame.setSize(400, 400);
  frame.setVisible(true);
  frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
  }

  public class MyAction implements ActionListener{
  public void actionPerformed(ActionEvent e){
  JOptionPane.showMessageDialog(frame,"techarena.in");
  }
  }
}
