Java / convert ISO-8601 (2010-12-16T13:33:50.513852Z) to Date object

by

tl;dr

Instant.parse( "2010-12-16T13:33:50.513852Z" )

java.time

The newer java.time classes can handle this string input.

The Z on the end is short for Zulu and means UTC, an offset of zero +00:00.

Instant

The Instant class represents a moment on the timeline in UTC with a resolution of nanoseconds (up to nine (9) digits of a decimal fraction). 

Instant instant = Instant.parse( "2010-12-16T13:33:50.513852Z" );

Time zone

You may want to apply a time zone ZoneId to get a ZonedDateTime. Search Stack Overflow for those class names to learn more, as well as for classes OffsetDateTime and DateTimeFormatter.

Conversion

Best to avoid the troublesome old legacy class of java.util.Date. But if you insist, call the new conversion methods added to the old classes.

java.util.Date date = java.util.Date.from( instant );

About java.time

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, Calendar, & SimpleDateFormat.

The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.

The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval, YearWeek, YearQuarter, and more.
