Java中的 WeekFields hashCode() 方法及示例

WeekFields 类的hashCode()方法用于返回此 WeekFields 的哈希码。它返回一个整数值，该整数值是此 ValueRange 实例的 hashCode 值。

句法：

public int hashCode()

参数：此方法不接受任何内容。

返回值：此方法返回整数值，即 hashCode 值。

下面的程序说明了 WeekFields.hashCode() 方法：
方案一：

// Java program to demonstrate
// WeekFields.hashCode() method
  
import java.time.DayOfWeek;
import java.time.temporal.WeekFields;
  
public class GFG {
    public static void main(String[] args)
    {
  
        // create WeekFields
        WeekFields weekFields
            = WeekFields.of(DayOfWeek.MONDAY, 1);
  
        // apply hashCode()
        int hashCode = weekFields.hashCode();
  
        // print results
        System.out.println("Hash Code:"
                           + hashCode);
    }
}

输出：

Hash Code:1

方案二：

// Java program to demonstrate
// WeekFields.hashCode() method
  
import java.time.DayOfWeek;
import java.time.temporal.WeekFields;
import java.util.Locale;
  
public class GFG {
    public static void main(String[] args)
    {
  
        Locale locale = new Locale("EN", "US");
  
        // create WeekFields
        WeekFields weekFields
            = WeekFields.of(locale);
  
        // apply hashCode()
        int hashCode = weekFields.hashCode();
  
        // print results
        System.out.println("Hash Code:"
                           + hashCode);
    }
}

输出：

Hash Code:43
