Creating a new line

I am learning how to save to a text file, and i am having some trouble creating a new line. I'm sure it is a quick and easy fix, but I can't find my problem. Here is my code.

Code:

---

package testsave;
import java.io.*;

public class TestSave {

    public static void main(String[] args) {
        String text = "Hello World!";
        String text1 = "Hello to you too!";
        try{
            FileWriter file = new FileWriter(text +".txt");
            file.write(text + " \n");
            file.write(text1 +" \n");
        }catch(IOException ex){
            ex.printStackTrace();
        }
    }
}

---

When i run this, i get :

Hello World! Hello to you too!

Thanks for the help!

i get...

Do you mean that this is what you see when you view the file in some viewer software? I ask because one OS inflicts on its users a text editor (Notepad) that cannot render newlines.

There are two ways to go:

* Use a BufferedWriter which has a newLine() method which will write whatever your Java runtime considers to be correct for your OS. (In which case you will have to deal with the different ways your file might be interpreted on different systems)

* Live with writing the newline as '\n'. (In which case your file is portable, but you will have to use a reliable text editor/viewer.)

[Edit]

Also, close file after you are finished using it. As written you may not see any output at all in the file.

when i say "i get" i mean to say, when i open the my .txt , it is what i see. I am using regular notepad for viewing the file i wrote. Thanks for the quick reply!

OK. Post back if you get stuck using BufferedWriter. PrintWriter is another way to go: System.out is an instance of PrintWriter, so you are already accustomed to how it works. Create one that writes to a file then println() will be good.

textpad is a good plain text editor for Windows.

Thanks! BufferedWriter worked great. I used the newLine(); method to make a new line, but what was the println() thing you were talking about. I don't understand that.

I was thinking along these lines:

Code:

---

package testsave;

import java.io.IOException;
import java.io.PrintWriter;

public class TestSave {

    public static void main(String[] args) {
        String text = "Hello World!";
        String text1 = "Hello to you too! (using a PrintWriter)";
        PrintWriter file = null;
        try {
            file = new PrintWriter(text +".txt");
            [color=blue]file.println(text);
            file.println(text1);[/color]
        } catch(IOException ex){
            ex.printStackTrace();
        } finally {
            if(file != null) {
                file.close();
            }
        }
    }
}

The effect is much the same as you would get by saying

Code:

---

System.out.println(text);
System.out.println(text1);

---

Closing the file in this way is covered in Oracle's Tutorial in the Exceptions lesson.

[Edit] I misspoke before: System.out is actually an instance of PrintStream, not PrintWriter. It doesn't make a lot of difference in this case as both have similar methods.

Oh ok, i get it. Thanks for all the help!

You're welcome.
