Java ZoneOffsetTransition toEpochSecond()用法及代碼示例

java.time.zone.ZoneOffsetTransition類的toEpochSecond()方法用於獲取此特定區域偏移過渡對象的紀元秒。

用法:

public long toEpochSecond()

參數：此方法不接受任何參數。

返回值：此方法返回此特定區域偏移過渡對象的紀元秒。

下麵是說明toEpochSecond()方法的示例：

範例1：

// Java program to demonstrate 
// toEpochSecond() 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 epoch second for this object 
        // by using toEpochSecond() method 
        long epocsec 
            = zonetrans1.toEpochSecond(); 
  
        // display the result 
        System.out.println( 
            "epoch second:"
            + epocsec); 
    } 
}

輸出：

epoch second:925010677

範例2：

// Java program to demonstrate 
// toEpochSecond() 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(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 epoch second for this object 
        // by using toEpochSecond() method 
        long epocsec 
            = zonetrans1.toEpochSecond(); 
  
        // display the result 
        System.out.println("epoch second:"
                           + epocsec); 
    } 
}

輸出：

epoch second:925010673
