# Java 程序：計算兩個時間段之間的差異 > 原文： [https://www.programiz.com/java-programming/examples/difference-time](https://www.programiz.com/java-programming/examples/difference-time) #### 在此程序中，您將學習計算 Java 中兩個時間段之間的時差。 ## 示例：計算兩個時間段之間的差異 ```java 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); } } ``` 運行該程序時，輸出為： ```java TIME DIFFERENCE: 12:34:55 - 8:12:15 = 4:22:40 ``` 在上述程序中，我們創建了一個名為`Time`的類，該類具有三個成員變量：`hours`，`minutes`和`seconds`。 顧名思義，它們分別存儲給定時間的`hours`，`minutes`和`seconds`。 `Time`類具有一個構造器，該構造器初始化`hours`，`minutes`和`seconds`的值。 我們還創建了一個靜態函數差異，該差異將兩個`Time`變量作為參數，找到該差異并將其作為`Time`類返回。
