java – 如何在print语句中使用零填充标志正确打印​​两个位置

如果想用零垫打印这个方法怎么做呢

int month,day;

public void  printNumeric()
{
  System.out.printf("month +"/" +day +" \n");
  // i would like the month if it is 5 to be 05 same thing with the day
}

解决方法

int month,day;

public void  printNumeric()
{
  System.out.printf("%02d/%02d\n",month,day);
  // i would like the month if it is 5 to be 05 same thing with the day
}
