java-time

I have a SpringBoot app. using Spring Initializer, embedded Tomcat, Thymeleaf template engine, and package as an executable JAR file. I have a domain object with 2 properties (initDate, endDate). I want to create 2 converters to deal with mySQL DB @Convert(converter = LocalDateTimeAttributeConverter.class) private LocalDateTime initDate; @Convert(converter = ZonedDateTimeAttributeConverter.class) private ZonedDateTime endDate; the converter 1 (is OK) @Converter public class LocalDateTimeAttributeConverter implements AttributeConverter<LocalDateTime, Timestamp> { @Override public Timestamp

Other answers here refer to Joda API. I want to do it using java.time . Suppose today's date is 26th Nov 2015-Thursday, when I add 2 business days to it, I want the result as Monday 30th Nov 2015. I am working on my own implementation but it would be great if something already exists! EDIT: Is there a way to do it apart from looping over? I was trying to derive a function like: Y = f(X1,X2) where Y is actual number of days to add, X1 is number of business days to add, X2 is day of the week (1-Monday to 7-Sunday) Then given X1 and X2 (derived from day of week of the date), we can find Y and

How to reduce one month from current date and want to sore in java.util.Date variable im using this code but it's shows error in 2nd line java.util.Date da = new Date(); da.add(Calendar.MONTH, -1); //error How to store this date in java.util.Date variable? Use Calendar: Calendar cal = Calendar.getInstance(); cal.add(Calendar.MONTH, -1); Date result = cal.getTime(); Starting from Java 8, the suggested way is to use the Date-Time API rather than Calendar . If you want a Date object to be returned: Date date = Date.from(ZonedDateTime.now().minusMonths(1).toInstant()); If you don't need exactly a

I get a UTC date with following format and how can convert this UTC date to my local time zone? my input date is 2015-03-17 06:00:00 +0000 and I tried the following coding its gives parsing exception. My code: DateFormat utcFormat = new SimpleDateFormat("dd-MM-yyyy HH:mm:ss 'Z'"); utcFormat.setTimeZone(TimeZone.getTimeZone("UTC")); Date date = utcFormat.parse("2015-03-17 06:00:00 +0000"); // java.text.DateFormat.parse(Unknown Source) utcFormat.setTimeZone(TimeZone.getDefault()); System.out.println(utcFormat.format(date)); You have two mistakes in your code. As others already mentioned you have

I'm aware that you can use DateUtils.formatElapsedTime(seconds) to convert a number of seconds into a String with the format HH:MM:SS . But are there any utility functions that let me perform the same conversion but without the seconds? For example, I want to convert 3665 seconds into 1:01 , even though it's exactly 1:01:05 . In other words, simply dropping the seconds part. Would strongly prefer an answer that points to a utility function (if one exists) rather than a bunch of home rolled algorithms. Based on the available information, you seem to be wanting to format a duration based value.
