周字段类的 hashCode() 方法用于返回该周字段的哈希代码。它返回一个整数值，该整数值是 ValueRange 实例的 hashCode 值。

语法:

public int hashCode()

参数:此方法不接受任何内容。

返回值:该方法返回一个整数值，即 hashCode 值。

下面的程序说明了 WeekFields.hashCode()方法: 程序 1:

// 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);
    }
}

Output:

Hash Code:1

程序 2:

// 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);
    }
}

Output:

Hash Code:43
