Syntax:
public int getDays()
Parameters: This method does not accepts any parameter.
Return Value: This function returns the number of days in the given period.
Below programs illustrate the above method:
Program 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);    }} |
Output:
25
Program 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);    }} |
Output:
365
