Java ZonedDateTime minusSeconds()用法及代码示例

ZonedDateTime类的minusSeconds()方法用于从此ZonedDateTime中减去秒数，并在减法后返回ZonedDateTime的副本。此方法在即时时间轴上起作用，并且减去one-second则返回前一秒的时间轴。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 minusSeconds(long seconds)

参数：此方法接受单个参数seconds，该参数代表要减去的秒，它可以为负。

返回值：此方法基于此日期时间并减去秒，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minusSeconds()方法：
示例1:

// Java program to demonstrate 
// ZonedDateTime.minusSeconds() 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"
                           + " subtracting seconds: "
                           + zoneddatetime); 
  
        // subtract 100 seconds 
        ZonedDateTime returnvalue 
            = zoneddatetime.minusSeconds(100); 
  
        // print result 
        System.out.println("ZonedDateTime after "
                           + " subtracting 100 seconds: "
                           + returnvalue); 
    } 
}

输出：

ZonedDateTime before subtracting seconds: 2018-12-06T19:21:12.123+05:30[Asia/Calcutta]
ZonedDateTime after subtracting 100 seconds: 2018-12-06T19:19:32.123+05:30[Asia/Calcutta]

示例2:

// Java program to demonstrate 
// ZonedDateTime.minusSeconds() 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"
                           + " subtracting seconds: "
                           + zoneddatetime); 
  
        // subtract -22 seconds 
        ZonedDateTime returnvalue 
            = zoneddatetime.minusSeconds(-22); 
  
        // print result 
        System.out.println("ZonedDateTime after "
                           + " subtracting -22 seconds: "
                           + returnvalue); 
    } 
}

输出：

ZonedDateTime before subtracting seconds: 2018-10-25T23:12:31.123+02:00[Europe/Paris]
ZonedDateTime after subtracting -22 seconds: 2018-10-25T23:12:53.123+02:00[Europe/Paris]
