Java Date Time - Duration toString() example

• Back to Duration  ↑

Duration toString() returns a string representation of this duration using ISO-8601 seconds based representation, such as PT8H6M12.345S.

The format of the string will be PTnHnMnS, where n is the relevant hours, minutes or seconds part of the duration.

Any fractional seconds are placed after a decimal point i the seconds section.

If a section has a zero value, it is omitted. The hours, minutes and seconds will all have the same sign.

Examples:

"20.345 seconds"                 -- "PT20.345S
"15 minutes" (15 * 60 seconds)   -- "PT15M"
"10 hours" (10 * 3600 seconds)   -- "PT10H"
"2 days" (2 * 86400 seconds)     -- "PT48H"

Syntax

toString has the following syntax.

public String toString()

Example

The following example shows how to use toString.

import java.time.Duration;
import java.time.LocalTime;
/*from  w  ww  .jav  a 2 s.  c o m*/
public class Main {
  public static void main(String[] args) {
    Duration duration = Duration.between(LocalTime.MIDNIGHT,LocalTime.NOON);
    System.out.println(duration.getSeconds());
    System.out.println(duration.toString());    
  }
}
