Java ZoneOffsetTransition getInstant()用法及代碼示例

java.time.zone.ZoneOffsetTransition類的getInstant()方法用於獲取表示兩個區域偏移量之間過渡的即時類型的對象。

用法:

public Instant getInstant()

參數：此方法不接受任何參數。

返回值：此方法返回表示兩個區域偏移量之間過渡的即時類型的對象。

下麵是說明getInstant()方法的示例：

範例1：

// Java program to demonstrate 
// getInstant() method 
  
import java.util.*; 
import java.io.*; 
import java.time.*; 
import java.time.chrono.*; 
import java.time.zone.*; 
  
public class GFG { 
    public static void main(String[] argv) 
    { 
  
        // creating and initializing 
        // the object of LocalDateTime 
        LocalDateTime loc 
            = LocalDateTime.of( 
                1999, 04, 25, 
                03, 24, 45, 0); 
  
        // creating and initializing 
        // the object of ZoneOffset 
        ZoneOffset off1 
            = ZoneOffset.ofTotalSeconds(8); 
  
        // creating and initializing 
        // the object of ZoneOffset 
        ZoneOffset off2 
            = ZoneOffset.ofTotalSeconds(12); 
  
        // creating and initializing 
        // ZoneOffsetTransition Object 
        ZoneOffsetTransition zonetrans1 
            = ZoneOffsetTransition.of( 
                loc, off1, off2); 
  
        // getting the instant between two transition 
        // by using getInstant() method 
        Instant inst = zonetrans1.getInstant(); 
  
        // display the result 
        System.out.println("Instant:" + inst); 
    } 
}

輸出：

Instant:1999-04-25T03:24:37Z

範例2：

// Java program to demonstrate 
// getInstant() method 
  
import java.util.*; 
import java.io.*;

        LocalDateTime loc 
            = LocalDateTime.of( 
                1999, 04, 25, 
                03, 24, 45, 0); 
  
        // creating and initializing 
        // the object of ZoneOffset 
        ZoneOffset off1 
            = ZoneOffset.ofTotalSeconds(12); 
  
        // creating and initializing 
        // the object of ZoneOffset 
        ZoneOffset off2 
            = ZoneOffset.ofTotalSeconds(8); 
  
        // creating and initializing 
        // ZoneOffsetTransition Object 
        ZoneOffsetTransition zonetrans1 
            = ZoneOffsetTransition.of( 
                loc, off1, off2); 
  
        // getting the instant between two transition 
        // by using getInstant() method 
        Instant inst = zonetrans1.getInstant(); 
  
        // display the result 
        System.out.println("Instant:" + inst); 
    } 
}

輸出：

Instant:1999-04-25T03:24:33Z
