Java 中 hoursimnutesseconds(int，int，int)方法的区域偏移量，示例

原文:https://www . geeksforgeeks . org/zone offset-of hours sminutessecondsint-int-int-method-in-Java-with-examples/

java.time 包中 ZoneOffset 类的of Horsimnutesseconds(int，int，int) 方法用于获取 ZoneOffset 的实例，使用以小时、分钟和秒为单位传递的偏移量作为参数。该方法将小时、分钟和秒作为 int 形式的参数，并将其转换为 ZoneOffset。

语法:

public static ZoneOffset
  ofHoursMinutesSeconds(int hours, 
                        int minutes,  
                        int seconds)

参数:该方法接受 3 个参数:

  • Hours : that is, the integer number of hours to be converted into a ZoneOffset instance. Its range is +18 to -18.
  • Minute : This is the int minute to be converted into a ZoneOffset instance. Its range is -59 to +59.
  • second : this is the int second to be converted into a ZoneOffset instance. The range is -59 to +59.

返回值:该方法返回从指定的小时、分钟和秒解析的区域偏移实例。

异常:如果小时、分、秒无效，此方法抛出日期时间异常。

下面的例子说明了 zoneoffset . of hours minutessconds()方法:

例 1:

// Java code to illustrate ofHoursMinutesSeconds() method

import java.time.*;

public class GFG {
    public static void main(String[] args)
    {

        // Get the hours, minutes and seconds
        int hours = 5;
        int minutes = 20;
        int seconds = 50;

        // ZoneOffset using ofHoursMinutesSeconds() method
        ZoneOffset zoneOffset
            = ZoneOffset
                  .ofHoursMinutesSeconds(hours,
                                         minutes,
                                         seconds);

        System.out.println(zoneOffset);
    }
}

输出:

+05:20:50

示例 2: 演示日期时间异常

// Java code to illustrate ofHoursMinutesSeconds() method

import java.time.*;

public class GFG {
    public static void main(String[] args)
    {

        // Get the invalid hours, minutes and seconds
        int hours = 20;
        int minutes = 5;
        int seconds = 0;

        try {
            // ZoneOffset using ofHoursMinutesSeconds() method
            ZoneOffset zoneOffset
                = ZoneOffset
                      .ofHoursMinutesSeconds(hours,
                                             minutes,
                                             seconds);
        }

        catch (Exception e) {
            System.out.println(e);
        }
    }
}

输出:

java.time.DateTimeException:
 Zone offset hours not in valid range:
 value 20 is not in the range -18 to 18
