下面的程序说明了上述方法。

程序1 :

// Java code to show the function getDays()// to get number of days from given periodimport java.time.Period;import java.time.temporal.ChronoUnit;  public class PeriodDemo {      // Function to get number of days of given period    static void getNumberOfDays(int year, int months, int days)    {        Period period = Period.of(year, months, days);        System.out.println(period.getDays());    }      // Driver Code    public static void main(String[] args)    {          int year = 8;        int months = 5;        int days = 25;          getNumberOfDays(year, months, days);    }}

输出:

25

程序2

// Java code to show the function getDays()// to get number of days from given periodimport java.time.Period;import java.time.temporal.ChronoUnit;  public class PeriodDemo {      // Function to get number of days of given period    static void getNumberOfDays(int year, int months, int days)    {        Period period = Period.of(year, months, days);        System.out.println(period.getDays());    }      // Driver Code    public static void main(String[] args)    {          int year = 0;        int months = 0;        int days = 365;          getNumberOfDays(year, months, days);    }}

输出:

365
