 public static void main(String[] args) {
     
      //i = baris pertama
        for (int i=1; i<=11; i++){
        System.out.print("*");
        }
        System.out.println();
        //i = baris, j= kolom
        int t = 5;
        for (int i=1; i<=t; i++){
            for (int j=5; j>=i; j--)
                System.out.print("*");
          
            for (int j=2; j<=i; j++)
                System.out.print(" ");
             for (int j=1; j<=i; j++)
                System.out.print(" ");
            for (int j=5; j>=i; j--)
                System.out.print("*");
            System.out.println();
        }
