Java Examples for java.time.format.DateTimeFormatter.ofPattern

The following java examples will help you to understand the usage of java.time.format.DateTimeFormatter.ofPattern. These source code samples are taken from different open source projects.

Example 1

Project: levelup-java-examples-master File: DateMinusMinutes.java View source code

@Test
public void subtract_minutes_from_date_in_java8() {
    LocalDateTime newYearsDay = LocalDateTime.of(2013, Month.JANUARY, 1, 0, 0);
    LocalDateTime newYearsEve = newYearsDay.minusMinutes(1);
    java.time.format.DateTimeFormatter formatter = java.time.format.DateTimeFormatter.ofPattern("MM/dd/yyyy HH:mm:ss S");
    logger.info(newYearsDay.format(formatter));
    logger.info(newYearsEve.format(formatter));
    assertTrue(newYearsEve.isBefore(newYearsDay));
}

Example 2

Project: edison-microservice-master File: JobRepresentation.java View source code

private String formatRuntime(OffsetDateTime started, OffsetDateTime stopped) {
    Duration duration = Duration.between(started, stopped);
    if (duration.toHours() >= 24) {
        return "> 24h";
    }
    LocalTime dateTime = LocalTime.ofSecondOfDay(duration.getSeconds());
    return humanReadable ? ofPattern("HH:mm:ss").format(dateTime) : ofPattern("HH:mm:ss").format(dateTime);
}

Example 3

Project: fullstop-master File: FetchAmiJob.java View source code

private Optional<LocalDate> getExpirationDate(final Image image) {
    // current implementation parse creation date from name + add 60 days support period
    return Optional.ofNullable(image.getName()).filter( name -> !name.isEmpty()).map(TAUPAGE_NAME_SPLITTER::splitToList).filter(// "Taupage-AMI-20160201-123456"
     list -> list.size() == 4).map( parts -> parts.get(2)).map( timestamp -> LocalDate.parse(timestamp, ofPattern("yyyyMMdd"))).map( creationDate -> creationDate.plusDays(60));
}
