一段有意思的代码

public class NumberDemo
{
 @SuppressWarnings("static-access")
 public static void main(String... args)
 {
  String nums = "123456789";
  for (int i = 1; i <= 9; i++)
  {
   String num = nums.substring(0, i);
   int i_num = Integer.valueOf(num);
   System.out.println(num.format("%9d*8+%d=%d", Integer.valueOf(num), i, i_num * 8 + i));
  }
 }
}
