Java ZonedDateTime plusSeconds()用法及代码示例


ZonedDateTime类的plusSeconds()方法用于在此ZonedDateTime中添加秒数,并在添加后返回ZonedDateTime的副本。此方法在即时时间轴上起作用,并且添加one-second会在一秒后返回时间轴。请注意,此方法与几天,几个月和几年使用的方法不同。此实例是不可变的,不受此方法调用的影响。

用法:

public ZonedDateTime plusSeconds(long seconds)

参数:此方法接受单个参数seconds,该参数代表要添加的秒数,可以为负数。


返回值:此方法基于此日期时间(加上秒)返回ZonedDateTime。

异常:如果结果超出支持的日期范围,则此方法将引发DateTimeException。

以下示例程序旨在说明plusSeconds()方法:
示例1:

// Java program to demonstrate 
// ZonedDateTime.plusSeconds() 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"
                           + " adding seconds: "
                           + zoneddatetime); 
  
        // add 3002 seconds 
        ZonedDateTime returnvalue 
            = zoneddatetime.plusSeconds(3002); 
  
        // print result 
        System.out.println("ZonedDateTime after "
                           + " adding seconds: "
                           + returnvalue); 
    } 
}
输出:

ZonedDateTime before adding seconds: 2018-12-06T19:21:12.123+05:30[Asia/Calcutta]
ZonedDateTime after adding seconds: 2018-12-06T20:11:14.123+05:30[Asia/Calcutta]

示例2:

// Java program to demonstrate 
// ZonedDateTime.plusSeconds() 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"
                           + " adding seconds: "
                           + zoneddatetime); 
  
        // add 52 seconds 
        ZonedDateTime returnvalue 
            = zoneddatetime.plusSeconds(52); 
  
        // print result 
        System.out.println("ZonedDateTime after "
                           + " adding seconds: "
                           + returnvalue); 
    } 
}
输出:

ZonedDateTime before adding seconds: 2018-10-25T23:12:31.123+02:00[Europe/Paris]
ZonedDateTime after adding seconds: 2018-10-25T23:13:23.123+02:00[Europe/Paris]
