plese tell me the control flow of this program

public class starForTest

{

    public static void main(String [] args)

    {

            for (int i=1; i<=9; i++)

            {

                    System.out.println();

                    for (int j=9; j>=i; j--)

                    {

                            System.out.print(" ");

                    }

             for (int k=1; k<=i; k++)

             {

                    System.out.print("*");

             }      

                            }

    System.out.println();   

    }

}

in this i is row num and j is column num... and what about k....? plese tell me the control flow

In your code, the i in for loop (int i=1; i<=9; i++) generates the nine rows to display the aestricks. Then, the j in for loop (int j=9; j>=i; j--) decreases the spaces by 1 throughout the rows. After that k in the last loop generates the aestricks in nine rows.
