Java ZoneOffsetTransition of()用法及代碼示例

java.time.zone.ZoneOffsetTransition類的of()方法用於借助本地日期時間，之前的偏移量和之後的偏移量來創建區域偏移量轉換的對象。

用法:

public static ZoneOffsetTransition of(LocalDateTime transition,
                                      ZoneOffset offsetBefore,
                                      ZoneOffset offsetAfter)

參數：此方法將以下參數作為參數。

transition:必須為其創建過渡的本地日期時間的對象。
offsetBefore:初始過渡的區域偏移對象。
offsetAfter:最終過渡的區域偏移對象。

返回值：此方法借助本地日期時間，之前的偏移量和之後的偏移量返回區域偏移量轉換的對象。

下麵是說明of()方法的示例：

範例1：

// Java program to demonstrate 
// of() 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 
        // by using of() method 
        ZoneOffsetTransition zonetrans1 
            = ZoneOffsetTransition.of( 
                loc, off1, off2); 
  
        // getting the string representation 
        // of this object 
        String str 
            = zonetrans1.toString(); 
  
        // display the result 
        System.out.println( 
            "zone offset transition:"
            + str); 
    } 
}

輸出：

zone offset transition:Transition[Overlap at 1999-04-25T03:24:45+00:00:12 to +00:00:08]

範例2：

// Java program to demonstrate 
// of() 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( 
                2018, 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 
        // by using of() method 
        ZoneOffsetTransition zonetrans1 
            = ZoneOffsetTransition.of( 
                loc, off1, off2); 
  
        // getting the string representation 
        // of this object 
        String str = zonetrans1.toString(); 
  
        // display the result 
        System.out.println( 
            "zone offset transition:"
            + str); 
    } 
}

輸出：

zone offset transition:Transition[Overlap at 2018-04-25T03:24:45+00:00:12 to +00:00:08]
