Writing JTextArea content into file

I have one JTextArea and a Submit button in Java Swing. Need to write the content of textarea into a file with line breaks. I got the output like, it is written as one string in the file.

try {
    BufferedWriter fileOut = new BufferedWriter(new FileWriter("filename.txt")); 
    String myString1 =jTextArea1.getText();
    String myString2 = myString1.replace("\r", "\n");

    System.out.println(myString2);

    fileOut.write(myString2);
    fileOut.close();
} catch (IOException ioe) {
    ioe.printStackTrace();
}

Please get me some suggestions

This is what i thought up of :

public void actionPerformed(ActionEvent event) {
BufferedWriter writer;
        try {
            writer = new BufferedWriter(new FileWriter("SimpleText.txt",
                    false));
            text.write(writer);
            writer.close();
            JOptionPane.showMessageDialog(null, "File has been saved","File Saved",JOptionPane.INFORMATION_MESSAGE);
            // true for rewrite, false for override

        } catch (IOException e) {
            JOptionPane.showMessageDialog(null, "Error Occured");
            e.printStackTrace();
        }
    }

Hope this helps

Why did you replace \r by \n ?

The line separator should be "\r\n".

Why not use JTextArea's built in write function?

JTextArea area = ...
try (BufferedWriter fileOut = new BufferedWriter(new FileWriter(yourFile))) {
    area.write(fileOut);
}

Replace all \r and \n with:

System.getProperty("line.separator")

This will make your code platform-independent and will write new lines to the files where necessary.

Edit: since you use BufferedWriter, you could also use the newLine() method
