The compareTo(Duration) method of Duration Class in java.time package is used to compare this duration with the duration passed as the parameter.
Syntax:
public int compareTo(Duration otherDuration)
Parameters: This method accepts a parameter otherDuration which is the duration to which this duration will be compared to.
Return Value: This method returns an int value where negative value means that otherDuration is larger than this value, zero means otherDuration is equal to this duration, and positive value means this duration is larger than the otherDuration.
Below examples illustrate the Duration.compareTo() method:
Example 1:
// Java code to illustrate compareTo() method  import java.time.Duration;  public class GFG {    public static void main(String[] args)    {          // Duration using parse() method        Duration duration1            = Duration.parse("P2DT3H4M");          // Duration using ofDays() method        Duration duration2            = Duration.ofDays(10);          // Compare the durations        // using compareTo() method        System.out.println(duration1                               .compareTo(duration2));    }} |
Output:
-1
Example 2:
// Java code to illustrate compareTo() method  import java.time.Duration;  public class GFG {    public static void main(String[] args)    {          // Duration using ofHours() method        Duration duration1            = Duration.ofHours(5);          // Duration using ofHours() method        Duration duration2            = Duration.ofHours(5);          // Compare the durations        // using compareTo() method        System.out.println(duration1                               .compareTo(duration2));    }} |
Output:
0
Example 3:
// Java code to illustrate compareTo() method  import java.time.Duration;  public class GFG {    public static void main(String[] args)    {          // Duration using ofDays() method        Duration duration1            = Duration.ofDays(5);          // Duration using ofHours() method        Duration duration2            = Duration.ofHours(5);          // Compare the durations        // using compareTo() method        System.out.println(duration1                               .compareTo(duration2));    }} |
Output:
1
