Console output in a matrix format

Question

public class dataarrange {
    public static void main(String args[]) {
        try {
            PrintStream myconsole = new PrintStream(new File("D://out.txt"));
            for (int i = 0; i < 10; i++) {
                double a = Math.sqrt(i);
                int b = 10 + 5;
                double c = Math.cos(i);
                myconsole.print(a);
                myconsole.print(b);
                myconsole.print(c);
            }
        } catch (FileNotFoundException ex) {
            System.out.println(ex);
        }
    }
}

In this programming code I generate a text file named out where I write down the output of dataarrange class. There is no error in code. As per code we get a,b,c for 10 times. I write down the value in a systematic way in the text file. The text file should look like a matrix which have 10 rows and 3 columns. But when I open the text file out.txt all data are in scatter way. They are written as a line not as a matrix format.

Desired output:

a    b    c

val1 val2 val3

val4 val5 val6

val7 val8 val9

So on...

But getting output val1 val2 val3 val4 val5 val6. How could I fix this problem?

You may also use the escape sequences \n \t but the above anwser with formatted string should be preferred

package test;

import java.io.File;
import java.io.FileNotFoundException;
import java.io.PrintStream;

public class DataRange {
    public static void main(String args[]) {

        try {
            PrintStream myconsole = new PrintStream(new File("out.txt"));
            for (int i = 0; i < 10; i++) {
                double a = Math.sqrt(i);

                int b = 10 + 5;
                double c = Math.cos(i);
                System.out.print("\t" + a);
                myconsole.print("\t" + a);
                System.out.print("\t" + b);
                myconsole.print("\t" + b);
                System.out.print("\t" + c);
                myconsole.print("\t" + c);
                myconsole.print("\n");
                System.out.println("\n");
                System.out.println("Completed");
            }
        } catch (FileNotFoundException ex) {
            System.out.println(ex);
        }
    }
}
