Java中的LocalTime直到()方法
可以使用until()Java中LocalTime类中的方法获得两个LocalTime对象之间的差异。此方法需要两个参数，即LocalTime对象的结束时间和Temporal单位。同样，它以指定的时间单位返回两个LocalTime对象之间的时差。
演示此的程序如下所示-
示例
import java.time.*;
import java.time.temporal.*;
public class Demo {
public static void main(String[] args) {
LocalTime lt1 = LocalTime.parse("10:15:30");
LocalTime lt2 = LocalTime.parse("12:21:30");
System.out.println("The first LocalTime is: " + lt1);
System.out.println("The second LocalTime is: " + lt2);
System.out.println("\nThe difference between two LocalTimes in hours is: " + lt1.until(lt2, ChronoUnit.HOURS));
}
}输出结果
The first LocalTime is: 10:15:30 The second LocalTime is: 12:21:30 The difference between two LocalTimes in hours is: 2
现在让我们了解上面的程序。
首先，显示两个LocalTime对象。然后使用该until()方法获得小时之间的差异并显示出来。演示这的代码片段如下-
LocalTime lt1 = LocalTime.parse("10:15:30");
LocalTime lt2 = LocalTime.parse("12:21:30");
System.out.println("The first LocalTime is: " + lt1);
System.out.println("The second LocalTime is: " + lt2);
System.out.println("\nThe difference between two LocalTimes in hours is: " + lt1.until(lt2, ChronoUnit.HOURS));
