Code
The code below shows how the formatDurationISO() works in Java.
import org.apache.commons.lang3.time.DurationFormatUtils;public class Main{public static void main(String[] args) {// Example 1long durationMillis = 1234542;System.out.printf("DurationFormatUtils.formatDurationISO(%s) = %s", durationMillis, DurationFormatUtils.formatDurationISO(durationMillis));System.out.println();// Example 2durationMillis = 0;System.out.printf("DurationFormatUtils.formatDurationISO(%s) = %s", durationMillis, DurationFormatUtils.formatDurationISO(durationMillis));System.out.println();}}
Output
The output of the code will be as follows:
DurationFormatUtils.formatDurationISO(1234542) = P0Y0M0DT0H20M34.542S
DurationFormatUtils.formatDurationISO(0) = P0Y0M0DT0H0M0.000S
Explanation
Example 1
duration in milliseconds - 1234542
The method returns P0Y0M0DT0H20M34.542S, i.e., the formatted duration in milliseconds to ISO 8601 period format.
Example 2
start milliseconds - 0end milliseconds - 12321
The method returns P0Y0M0DT0H0M12.321S, i.e., the formatted duration in milliseconds to ISO 8601 period format.
