以下示例程序旨在說明上述方法：

程序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); 
    } 
}

輸出：

[Years, Months, Days]

程序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); 
    } 
}
