在此程序中，您将学习计算Java中两个时间段之间的时差。
示例：计算两个时间段之间的时差
public class Time {
int seconds;
int minutes;
int hours;
public Time(int hours, int minutes, int seconds) {
this.hours = hours;
this.minutes = minutes;
this.seconds = seconds;
}
public static void main(String[] args) {
Time start = new Time(12, 34, 55),
stop = new Time(8, 12, 15),
diff;
diff = difference(start, stop);
System.out.printf("TIME DIFFERENCE: %d:%d:%d - ", start.hours, start.minutes, start.seconds);
System.out.printf("%d:%d:%d ", stop.hours, stop.minutes, stop.seconds);
System.out.printf("= %d:%d:%d\n", diff.hours, diff.minutes, diff.seconds);
}
public static Time difference(Time start, Time stop)
{
Time diff = new Time(0, 0, 0);
if(stop.seconds > start.seconds){
--start.minutes;
start.seconds += 60;
}
diff.seconds = start.seconds - stop.seconds;
if(stop.minutes > start.minutes){
--start.hours;
start.minutes += 60;
}
diff.minutes = start.minutes - stop.minutes;
diff.hours = start.hours - stop.hours;
return(diff);
}
}运行该程序时，输出为：
TIME DIFFERENCE: 12:34:55 - 8:12:15 = 4:22:40
在上面的程序，我们已经创建了一个名为Time类有三个成员变量hours，minutes和seconds。正如名字所暗示的，它们分别给定的时间存储hours，minutes和seconds。
Time类具有一个构造函数，用于初始化hours，minutes和seconds。
我们还创建了一个静态函数difference，它接受两个时间变量作为参数，查找差异并将其作为Time类返回
