ChronoZonedDateTime類的toInstant()方法用於將此ChronoZonedDateTime轉換為Instant。

用法:

default Instant toInstant()

參數:此方法不接受任何參數。


返回值:此方法返回Instant,它與此ChronoZonedDateTime表示相同。

以下示例程序旨在說明toInstant()方法:

示例1:

// Java program to demonstrate 
// ChronoZonedDateTime.toInstant() method 
  
import java.time.*; 
import java.time.chrono.*; 
import java.time.chrono.*; 
  
public class GFG { 
    public static void main(String[] args) 
    { 
  
        // create ChronoZonedDateTime object 
        ChronoZonedDateTime time 
            = ZonedDateTime 
                  .parse( 
                      "2018-12-06T19:21:12.123+05:30[Asia/Calcutta]"); 
  
        // print ChronoZonedDateTime 
        System.out.println("ChronoZonedDateTime: "
                           + time); 
  
        // print result 
        System.out.println("Instant: "
                           + time.toInstant()); 
    } 
}
輸出:
ChronoZonedDateTime: 2018-12-06T19:21:12.123+05:30[Asia/Calcutta]
Instant: 2018-12-06T13:51:12.123Z

示例2:

// Java program to demonstrate 
// ChronoZonedDateTime.toInstant() method 
  
import java.time.*; 
import java.time.chrono.*; 
import java.time.chrono.*; 
  
public class GFG { 
    public static void main(String[] args) 
    { 
  
        // create ChronoZonedDateTime object 
        ChronoZonedDateTime time 
            = ZonedDateTime.parse( 
                "1918-10-25T23:12:38.543+02:00[Europe/Paris]"); 
  
        // print ChronoZonedDateTime 
        System.out.println("ChronoZonedDateTime: "
                           + time); 
  
        // print result 
        System.out.println("Instant: "
                           + time.toInstant()); 
    } 
}
輸出:
ChronoZonedDateTime: 1918-10-25T23:12:38.543Z[Europe/Paris]
Instant: 1918-10-25T23:12:38.543Z
