這次要做出像這樣的九九乘法表:

        for (int k=0; k<2; k++) {
     	      for (int j=1; j<=9; j++) {
           	      for (int i=2; i<=5; i++) {
                 	     int newi = i + k * 4;
                 	     int result = newi * j;
                         System.out.printf("%d x %d = %d\t" , newi, j, result);
           		  }
          	      System.out.println();
    	      }
              System.out.println("-----");
        }



    }

}
