Java ZoneOffsetTransition getOffsetAfter()用法及代碼示例

java.time.zone.ZoneOffsetTransition類的getOffsetAfter()方法用於在轉換發生後獲取第二個偏移區域的偏移值。第一個和第二個偏移量是指在創建ZoneOffsetTransition對象時傳遞的值。

用法:

public ZoneOffset getOffsetAfter()

參數：此方法不接受任何參數。

返回值：此方法在轉換發生後返回第二個區域偏移量的偏移值。它不返回Null。

下麵是說明getOffsetAfter()方法的示例：

範例1：

// Java program to demonstrate 
// getOffsetAfter() 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 offset after value 
        // by using getOffsetAfter() method 
        ZoneOffset off 
            = zonetrans1.getOffsetAfter(); 
  
        // Display the result 
        System.out.println( 
            "Zoneoffset after transition:"
            + off); 
    } 
}

輸出：

Zoneoffset after transition:+00:00:12

範例2：

// Java program to demonstrate 
// getOffsetAfter() 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 offset after value 
        // by using getOffsetAfter() method 
        ZoneOffset off 
            = zonetrans1.getOffsetAfter(); 
  
        // Display the result 
        System.out.println( 
            "Zoneoffset after transition:"
            + off); 
    } 
}

輸出：

Zoneoffset after transition:+00:00:08
