How can I convert this date to Java?

Question

I want to convert:

2010-03-15T16:34:46Z

into something like 5 hours ago

How to do it in Java?

Answer 1

JodaTime supports custom format parsing. See DateTimeFormatterBuilder and DateTimeBuilder.parseDateTime ().

Once you have a DateTime, you can create a Duration or Period from this and the current time and use a different formatter for beautiful printing. See the Example PeriodFormatter referenced by BalusC in the comments above.]

     Calendar calendar = new GregorianCalendar(2010,Calendar.March,15, 16,34,46);
     calendar.add(Calendar.HOUR,-5);

Answer 4

TL;DR

Duration.between(
    Instant.parse( "2010-03-15T16:34:46Z" ) , 
    Instant.now() 
)     
.toHoursPart()    // returns a `int` integer number. 
+ " hours ago"
