例：

// Java program to demonstrate the example
// of List getUnits() method of Duration
import java.time.*;
import java.util.*;
import java.time.temporal.*;
public class GetUnitsOfDuration {public static void main(String args[]) {// Instantiates two Duration objects
Duration du1 = Duration.ofHours(1);
Duration du2 = Duration.parse("P1DT24H60M60S");
// Display du1 and du2
System.out.println("du1: " + du1);
System.out.println("du2: " + du2);
// get a list of units supported
// by this Duration du1
List list_of_units = du1.getUnits();
// Display list_of_units
System.out.println("du1.getUnits(): " + list_of_units);
// gets a list of units supported
// by this Duration du2
list_of_units = du2.getUnits();
// Display list_of_units
System.out.println("du2.getUnits(): " + list_of_units);
}
}

Output
