hello!
I have a main window ,by clicking on (add new item) , another window
open to fill the form
on clicking on (save to file),my form will be saved in text file.
if I open this text file using notepad for example,then I found my data
stored but concatenated
although I add to the saved string "\n" [hint:you will find two ## to
direct u to this line in
                                                   my code text]
if I change it to "\n\n" then my data is stored in separate lines which
I need.
the Problem that when I read the saved file by clicking on "update data
item" ,the returned
data in the form is not  as saved

MY CODE:
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
import java.io.*;
