Java ZoneOffsetTransition of()用法及代码示例

java.time.zone.ZoneOffsetTransition类的of()方法用于借助本地日期时间，之前的偏移量和之后的偏移量来创建区域偏移量转换的对象。

用法:

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

参数：此方法将以下参数作为参数。

transition:必须为其创建过渡的本地日期时间的对象。
offsetBefore:初始过渡的区域偏移对象。
offsetAfter:最终过渡的区域偏移对象。

返回值：此方法借助本地日期时间，之前的偏移量和之后的偏移量返回区域偏移量转换的对象。

下面是说明of()方法的示例：

范例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); 
    } 
}

输出：

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

范例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); 
    } 
}

输出：

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