how to save output (from TextField) to a particular Folder as txt file

hi,
i m facing a small prob in GUI, need to save my output to a particular folder.

below this code showing the square of any integer in TextField named: "resultField". i've a button "save" that need to save the result from that TextField, suppose in my "c:\Repository " folder as a txt file.

In addition, the name of the txt file can be same as given input integer. Example: 77, 99, .. whatever the input integer.

how can i do this ?? pls help...

Code:

---

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

public class SaveData extends Frame implements ActionListener {

private TextField inputField, resultField;
private Button saveButton, squareButton, exitButton;

  SaveData(String s) {
    super(s);
       
    setLayout(new GridLayout(3, 3, 5, 3));
       
    add(new Label("Type in an integer: "));
    inputField= new TextField();  add(inputField);
       
        squareButton=new Button("Square"); add(squareButton); squareButton.addActionListener(this);
       
        resultField=new TextField(); add(resultField);
       
        saveButton=new Button("SAVE"); add(saveButton); saveButton.addActionListener(this);

    exitButton=new Button("Exit"); add(exitButton); exitButton.addActionListener(this);
 
       
        setSize(250,130);
        setLocation(600,200);
    setVisible(true); }
       
       
  public void actionPerformed(ActionEvent e) {
  if (e.getSource()==squareButton) {
  int x=Integer.parseInt(inputField.getText());
  resultField.setText(Integer.toString(x*x));  }
 
  else if (e.getSource()==exitButton) {  this.setVisible(false);  this.dispose(); }
 
  }
 
 
  public static void main(String args[]){
  new SaveData("test");
  }
}

You can write information to a file using FileWriter like so:

Code:

---

public void saveData(String name, String data)
{
FileWriter writer = new FileWriter(new File("C:\\Repository\\" + name + ".txt");
writer.write(data);
writer.flush();
writer.close();
}

If you want more info on File Handling, there is an insightful tutorial on it on the java.sun.com website: Lesson: Basic I/O (The Java™ Tutorials > Essential Classes)
