把时间为3时65分15秒转为4时5分15秒的程序，可是输出的结果不对呀！

{
this.minutes+=(int)(this.seconds/60);//你的原句:minutes+=seconds%60分析一下为什么会错 //这是你的句2
this.seconds=this.seconds%60;//s为计算后的值,如果s没有大于60,计算失误了. 这一步计算之后,seconds已经为5了,下面的计算肯定会错,//这是你的句1
//句1和句2的顺序要调过来,因为句1在上面的时候seconds的值已经被取模过,已经变为>60的值了.句2的操作完全不起作用了

错的算法有点多啊,我都改过来了,你自己看看
