    Default Inverted Right Triangle

    Making a much larger program with a menu to determine what * triangle you would like but can not get the triangle like this to work:

    **********
    -*********
    --********
    ---*******
    ----******
    -----*****
    ------****
    -------***
    -------- **
    ----------*

    Without the " - "
    It keeps printing out in a straight line be grateful if someone could point me in the right direction.
    public class tester
    {
        public static void main(String[] args)
        {
          final int x = 10;
          for (int row = 0; row < x; row ++){
            for (int blank = 1; blank <= row; blank ++){
              System.out.print (" ");
            }
            for (int a = x - row; a > 0; a --){
              System.out.print ("*");
            }
            }
    }
    }

    It keeps printing out in a straight line
    Call the println() method to have the next String go on the next line
    Or print a "\n" character to have the following String go on the next line.
    If you don't understand my answer, don't ignore it, ask a question.

                    System.out.print("*");

    Add a "\n" to the String where you want the next String on the next line.
