This star pyramid java program has nested loop implementation. It is implemented in following steps

1.    Create a outer loop for number of rows entered by the user
   1. First inner loop to print space in decreasing order
   2. second and third for loop print stars with one space.

import java.util.Scanner;
public class StarPyramid
{
    public static void main(String args[])
    {
        Scanner scan = new Scanner(System.in);
        System.out.print("Enter Number of Rows : ");
        int n = scan.nextInt();

        for (int i = 1; i<=n ; i++) { 
            for (int j = i; j<=n; j++) {
                System.out.print(" ");
            }
            for (int j = 1; j< i; j++) { 
                System.out.print("* ");
            }
            for (int j = 1; j<=i; j++) {
                System.out.print("* ");
            }
            System.out.println();
        }
    }
}
