Below programs illustrate the above method:



Program 1:




// Java code to show the function getUnits()
// to get the set of units supported by period
  
import java.time.Period;
import java.time.temporal.ChronoUnit;
  
public class PeriodDemo {
  
    // Function to get the set of units supported by period
    static void getNumberOfDays(int year, int months, int days)
    {
        Period period = Period.of(year, months, days);
        System.out.println(period.getUnits());
    }
  
    // Driver Code
    public static void main(String[] args)
    {
        int year = 1;
        int months = 13;
        int days = 36;
  
        getNumberOfDays(year, months, days);
    }
}
Output:
[Years, Months, Days]

Program 2:




// Java code to show the function getUnits()
// to get the set of units supported by period
  
import java.time.Period;
import java.time.temporal.ChronoUnit;
  
public class PeriodDemo {
  
    // Function to get the set of units supported by period
    static void getNumberOfDays(int year, int months, int days)
    {
        Period period = Period.ofDays(days);
        System.out.println(period.getUnits());
    }
  
    // Driver Code
    public static void main(String[] args)
    {
        int year = 0;
        int months = 0;
        int days = 0;
  
        getNumberOfDays(year, months, days);
    }
