Question

I can print line by line using toString to the console, but how come it doesn’t do the same when I put it in a textfile?

public class NewClass
{

    @Override
    public String toString()
    {
        return ("John " + "\n" + "jumps " + "\n" + "fences");
    }
}


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


public class Sandbox
{
    public static void main(String[] args) throws IOException
    {
        NewClass object = new NewClass();            

        FileWriter file = new FileWriter("output.txt");
        PrintWriter output = new PrintWriter(file);
        output.println(object.toString());    
        output.close(); 
        System.out.println(object.toString());

    }
}

CONSOLE OUTPUT:

John

jumps

fences

output.txt

John jumps fences

Since you are on Windows, instead of \n use \r\n (carriage return + line feed).

Or better yet, use System.getProperty("line.separator") to obtain the sequence used by operating system to separate lines in text files.
