java writing to a text file

Question

I would like the following to be printed

test1

test2

test3

test4

But I can't seem to get the text to the next line.

Please help

import java.io.*;

public class MainFrame {
    public static void main(String[] args) {
        try {
        BufferedWriter out = new BufferedWriter(new FileWriter("file.txt"));
            for (int i = 0; i < 4; i++) {
                out.write("test " + "\n");
            }
            out.close();
        } catch (IOException e) {}
    }
}

Answer 1

Try out.newLine();

So, it would be

for (int i = 0; i < 4; i++) {
    out.write("test " + "\n");
    out.newLine();
}

Answer 2

You need have two \n\n to have a blank line. Try

out.write("test " + "\n\n");

In your case(with one \n), it will break the current line and move to a new line(which is the next line) but the blank line will not come.

The newline character can be depended on the platform, so it is better to get the new line character from the java system properties using

public static String newline = System.getProperty("line.separator");
