I made a NotePad program. The problem is it doesn't save in .txt format, It save as a file with no format. But it can open .txt files. How can i fix it? Here is my work.

import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
import java.util.Scanner;
import java.io.*;

public class NotePad extends JFrame {

    private JTextArea noteArea;


    public static void main(String[] args) {
        NotePad p = new NotePad();
        p.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        p.setSize(500,300);
        p.setVisible(true);
    }


    public NotePad() {
        super("Java Notepad");
        setLayout(new BorderLayout());
        noteArea = new JTextArea("",20,20);
        noteArea.setWrapStyleWord(true);
        noteArea.setLineWrap(true);

        Font font = new Font("sanserif", Font.BOLD,14);
        noteArea.setFont(font);

        JScrollPane scroller = new JScrollPane(noteArea);
        scroller.setVerticalScrollBarPolicy(ScrollPaneConstants.VERTICAL_SCROLLBAR_ALWAYS);
        scroller.setHorizontalScrollBarPolicy(ScrollPaneConstants.HORIZONTAL_SCROLLBAR_NEVER);
        add(scroller,BorderLayout.CENTER);


        JMenuBar menuBar = new JMenuBar();
        JMenu fileMenu = new JMenu("File");
        JMenuItem openMenu = new JMenuItem("Open");
        openMenu.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent ae) {
                JFileChooser openFile = new JFileChooser();
                openFile.showOpenDialog(new NotePad());
                loadFile(openFile.getSelectedFile());
            }


        });
        JMenuItem saveMenu = new JMenuItem("Save");
        saveMenu.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent ae) {
                JFileChooser saveFile = new JFileChooser();
                saveFile.showSaveDialog(new NotePad());
                fileSaved(saveFile.getSelectedFile());
            }

        });

        JMenuItem exitMenu = new JMenuItem("Close");
        exitMenu.addActionListener(new ActionListener(){
            public void actionPerformed(ActionEvent ae) {
                System.exit(0);
            }

        });

        fileMenu.add(openMenu);
        fileMenu.add(saveMenu);
        fileMenu.add(exitMenu);
        menuBar.add(fileMenu);
        this.setJMenuBar(menuBar);

    }

    public void loadFile(File file) {
        noteArea.setText("");
        try {

            BufferedReader read = new BufferedReader(new FileReader(file));
            String line = null;

            while((line =read.readLine())!=null) {
                noteArea.append(line +"\n");
            }
            read.close();
        }   
        catch (Exception e) {
        System.out.println("Error " + e.toString());
        }
    }


    public void fileSaved(File file) {
        try {
            PrintWriter writer = new PrintWriter(file);
            String[] lines  = noteArea.getText().split("\\n");
            for (String ) {

                writer.println(words);

            }
            writer.close();
        } catch (Exception e) {
            System.out.println("Error " + e.toString());
        }
    }
}

btw I can't post my question because of not explaning the scenario according to the site. So there. Thanks for the help
