java - 如何解决这个问题？ java作业

Question

我有作业

这是我的问题

我的代码是

public class DisplayTime {

    public static void main(String[] args) {        
        int seconds = 290;
        int hour = seconds/60/60;
        int minute = seconds/60;

        seconds = seconds%60;      

        System.out.printf("The amount of [ 290 ] seconds are %02d:%02d:%02d\n",hour,minute,seconds);

         seconds = 7650;
         hour = seconds/60/60;
         minute  = seconds/60;

         seconds = seconds%60;

         System.out.printf("The amount of [ 7650 ] seconds are %02d:%02d:%02d\n",hour,minute,seconds);
    }
}

我在 7650 中的输出不一样，为什么？ :(

我的解决方案是真的吗？

正如 @Balwinder 在他的评论中提到的，您最好有一个接受秒数并打印出格式化显示时间的辅助方法。下面的代码只需几行即可完成此任务。

public static void printHMS(int secs) {
    int seconds = secs % 60;
    int minutes = (secs / 60) % 60;
    int hours   = (secs / 60) / 60;

    System.out.printf("The amount of [ %d ] seconds are %02d:%02d:%02d\n", secs, hours, minutes, seconds);
}

public static void main(String args[]) {
    printHMS(290);
    printHMS(7650);
}

输出:

The amount of [ 290 ] seconds are 00:04:50
The amount of [ 7650 ] seconds are 02:07:30
