LocalDate.parse() method by default use ISO format, so no need for a DateTimeFormatter instance LocalDate localDate = LocalDate.parse( new SimpleDateFormat("yyyy-MM-dd").format(date) ) It involves multiple steps though :ġ) format Date to String using SimpleDateFormatĢ) Create LocalDate from formatted String If you like to work with String and good at String to Date conversion, then you can follow this route. ZonedDateTime zonedDateTime = gregorianCalendar.toZonedDateTime() GregorianCalendar gregorianCalendar = (GregorianCalendar) Calendar.getInstance() You can also use Java’s old Calendar API to convert to LocalDate in Java 8 as shown below : Why those magic numbers? because in old Date API, years start with 1900 and month starts with 0. LocalDate current = LocalDate.of(d.getYear() + 1900, getMonth() + 1, getDate()) LocalDate ld = new ( new ().getTime())īy the way, if you have a really good understanding of Java’s old Date API then you can also use this shortcut to convert a to LocalDate in Java 8 :ĭate d = new (new ().getTime()) You can even combine these two steps together as shown below : Since it’s also easy to convert between and, we will use the same trick to convert Date to LocalDate in the following two steps :ġ) Convert to Ģ) Convert to Surprisingly, it’s really easy to convert a to in Java 8, becuase JDK 8 has added a convenience method toLocalDate() into this class. It’s equivalent to the Instant class in the new Java Date API and that’s why you have a direct conversion method between Date and Instant in Java 8.Īnyway, it’s not hard to convert a to in Java 8, in fact, there are multiple ways which we will explore in this tutorial. There is a reason for it, even though says it’s a Date it’s not, becuase it’s just a millisecond value since midnight at the start of 1970 GMT. DateTime.java by Shaharia Azam guys, one of the challenges Java programmers face while using the new Java 8 Date and time API, JSR-310 in the existing Java application is the conversion between and and other classes.Įven though the library has everything you would expect, it doesn’t have a direct conversion method between old Date and new LocalDate. Let’s write a simple class which will convert our timezone to another timezone in Java. May be it will help you to work with Java UTC timezone. Here is the script I have written myself. That’s why I have prepared this article for you so you don’t need to spent too much time to figure it out for UTC timezone conversion in Java. I also faced similar types of problems multiple times while I was working with one of my Java library. Getting date and time in various timezoneīut don’t be frustrated.Convert java timezone from UTC to another timezone. Here is some use-cases that requires java date time conversion – In Java, it’s not so easy to work with Date Time conversion. And timezone conversion and other date time related operation is one of the most important task for mostly every software we develop. Working with date and time is a regular stuff we all do as a software engineer. However, I am not an advanced Java programmer but I brought some pieces from everywhere and build a small things that helped me to work with one of my practice project easily. Due to it’s huge library and extensive community, it’s one of the best used language I have ever seen. It’s also one of the oldest programming languages. Java is one of the most popular programming language in the world.
