  public static void main(String[] args) {
for (int a=0;a<2;a++) {
		System.out.print("  ");
		if (a != 1) {
			for (int b=0;b<7;b++) {
				System.out.print("*");
					for (int c=0;c<=b;c++) {
			 		 System.out.print("   ");
				  	 }
					  System.out.println("* ");
					}
 
		}else{
		for (int d=0;d<7;d++) {
				System.out.print("* ");
					for (int c=7;c>=d;c--) {
					 	System.out.print("  ");
						  	 }
						 System.out.println("* ");
 
							}
