Java ZoneOffsetTransitionRule hashCode()用法及代碼示例

java.time.zone.ZoneOffsetTransitionRule類的hashCode()方法用於獲取此區域偏移量轉換規則對象的哈希碼。

用法:

public int hashCode()

參數：此方法不接受任何參數。

返回值：此方法返回此區域偏移量轉換規則對象的哈希碼。

下麵是說明hashCode()方法的示例：

範例1：

// Java program to demonstrate 
// hashCode() 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 
        // ZoneOffsetTransitionRule Object 
        ZoneOffsetTransitionRule zonetrans1 
            = ZoneOffsetTransitionRule 
                  .of( 
                      Month.JANUARY, 12, 
                      DayOfWeek.SUNDAY, 
                      LocalTime.of(03, 24, 45), 
                      false, 
                      ZoneOffsetTransitionRule 
                          .TimeDefinition 
                          .STANDARD, 
                      ZoneOffset.ofTotalSeconds(8), 
                      ZoneOffset.ofTotalSeconds(17), 
                      ZoneOffset.ofTotalSeconds(12)); 
  
        // getting the hash code 
        // by using hashCode() method 
        int hash = zonetrans1.hashCode(); 
  
        // display the result 
        System.out.println("hash code:" + hash); 
    } 
}

輸出：

hash code:402556303

範例2：

// Java program to demonstrate 
// hashCode() 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 
        // ZoneOffsetTransitionRule Object 
        ZoneOffsetTransitionRule zonetrans1 
            = ZoneOffsetTransitionRule 
                  .of( 
                      Month.JANUARY, 12, 
                      DayOfWeek.SUNDAY, 
                      LocalTime.of(06, 24, 45), 
                      false, 
                      ZoneOffsetTransitionRule 
                          .TimeDefinition 
                          .STANDARD, 
                      ZoneOffset.ofTotalSeconds(8), 
                      ZoneOffset.ofTotalSeconds(17), 
                      ZoneOffset.ofTotalSeconds(12)); 
  
        // getting the hash code 
        // by using hashCode() method 
        int hash = zonetrans1.hashCode(); 
  
        // display the result 
        System.out.println("hash code:" + hash); 
    } 
}

輸出：

hash code:756450703
