Help with this method please!

Write a public static method named starPrinter that will take an int as a parameter and print lines of stars as shown below.

The header of the method will be public static void printStars(int n) .

e.g.
If the value of n is 5, then the method should print
*
***
*****
*******
*********

If the value of n is 3, then the method should print
*
***
*****

Please help!

it actually has to be shaped like a pyramid, the text format of this forum won't let me post the stars that way but it should look like a pyramid, not flat on one side like that

It should look like this:

What about using simple code tags instead?

Java Code:

    *
   ***
  *****
 *******
*********

btw why did you post this in the 'advanced' section?

kind regards,

Jos

I feel like this is a bad idea giving this away so easily, but what the hay.

read this and try to understand it, post if you have questions:

Java Code:

    public static void printPyramid (int n)
    {
        for (int i = 0 ; i < n ; i++)
        {
            for (int j = 0 ; j < n - 1 - i ; j++)
            {
                System.out.print (" ");
            }
            for (int j = 0 ; j < i * 2 + 1 ; j++)
            {
                System.out.print ("*");
            }
            System.out.println ("");

        }
    }
