Java ZonedDateTime withMinute()用法及代码示例

ZonedDateTime类的withMinute()方法用于更改此ZonedDateTime中的minute-of-hour,并在此操作后返回ZonedDateTime的副本。此方法在本地时间线上操作,更改本地日期时间的minute-of-hour,并在此操作后更改本地日期时间使用区域ID获取偏移量,将其转换回ZonedDateTime。当转换回ZonedDateTime时,如果本地日期时间重叠,则将尽可能保留偏移量,否则将使用较早的偏移量。此实例是不可变的,不受此方法调用的影响。

用法:

public ZonedDateTime withMinute(int minute)

参数:此方法接受一个表示要设置在结果中的minute-of-hour的参数分钟,范围是0-59。


返回值:此方法基于此日期时间和所请求的分钟返回ZonedDateTime。

异常:如果minute-of-hour值无效,或者minute-of-hour对于year-year无效,则此方法引发DateTimeException。

以下示例程序旨在说明withMinute()方法:
示例1:

// Java program to demonstrate 
// ZonedDateTime.withMinute() method 
  
import java.time.*; 
  
public class GFG { 
    public static void main(String[] args) 
    { 
  
        // create a ZonedDateTime object 
        ZonedDateTime zoneddatetime 
            = ZonedDateTime.parse( 
                "2018-12-06T19:21:12.123+05:30[Asia/Calcutta]"); 
  
        // print instance 
        System.out.println("ZonedDateTime before"
                           + " alter minute: "
                           + zoneddatetime); 
  
        // alter minute to 2 
        ZonedDateTime returnvalue 
            = zoneddatetime.withMinute(2); 
  
        // print result 
        System.out.println("ZonedDateTime after "
                           + "alter minute: "
                           + returnvalue); 
    } 
}
输出:

ZonedDateTime before alter minute: 2018-12-06T19:21:12.123+05:30[Asia/Calcutta]
ZonedDateTime after alter minute: 2018-12-06T19:02:12.123+05:30[Asia/Calcutta]

示例2:

// Java program to demonstrate 
// ZonedDateTime.withMinute() method 
  
import java.time.*; 
  
public class GFG { 
    public static void main(String[] args) 
    { 
  
        // create a ZonedDateTime object 
        ZonedDateTime zoneddatetime 
            = ZonedDateTime.parse( 
                "2018-10-25T23:12:31.123+02:00[Europe/Paris]"); 
  
        // print instance 
        System.out.println("ZonedDateTime before"
                           + " alter minute: "
                           + zoneddatetime); 
  
        // alter minute to 50 
        ZonedDateTime returnvalue 
            = zoneddatetime.withMinute(50); 
  
        // print result 
        System.out.println("ZonedDateTime after "
                           + "alter minute: "
                           + returnvalue); 
    } 
}
输出:

ZonedDateTime before alter minute: 2018-10-25T23:12:31.123+02:00[Europe/Paris]
ZonedDateTime after alter minute: 2018-10-25T23:50:31.123+02:00[Europe/Paris]
