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));
}
}
}
