Java Period hashCode()方法及示例

Java中Period类的hashCode()方法用于获取该周期生成的hashCode。

语法

public int hashCode()

参数： 该方法不接受任何参数。

返回值： 该方法返回为给定周期生成的hashCode。

以下程序说明了Java中的hashCode()方法。

程序1 :

// Java code to show the function hashCode()// to get the hashCode for the given period  import java.time.Period;import java.time.temporal.ChronoUnit;  public class PeriodDemo {      // Function to generate hashCode for the given period    static void getNumberOfDays(int year, int months, int days)    {        Period period = Period.of(year, months, days);        System.out.println(period.hashCode());    }      // Driver Code    public static void main(String[] args)    {        int year = 12;        int months = 3;        int days = 31;          getNumberOfDays(year, months, days);    }}

输出:

2032396

程序2 :

// Java code to show the function hashCode()// to get the hashCode for the given period  import java.time.Period;import java.time.temporal.ChronoUnit;  public class PeriodDemo {      // Function to generate hashCode for the given period    static void getNumberOfDays(int year, int months, int days)    {        Period period = Period.of(year, months, days);        System.out.println(period.hashCode());    }      // Driver Code    public static void main(String[] args)    {        int year = -12;        int months = 3;        int days = 31;          getNumberOfDays(year, months, days);    }}

输出:

2032372
