Java Period getDays()方法及示例

Java中Period类的getDays()方法用于获取当前周期的天数，该方法与之配合使用。

语法

public int getDays()

参数： 该方法不接受任何参数。

返回值： 该函数返回给定周期内的天数。

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 period
import 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 period
import 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
