You can use from bellow code for date and time : DateFormat dateFormat = new SimpleDateFormat("yyyy/MM/dd HH:mm:ss") You may find some useful classes here such as Interval, YearWeek, YearQuarter, and more.
This project is a proving ground for possible future additions to java.time. The ThreeTen-Extra project extends java.time with additional classes.

For earlier Android (Later versions of Android bundle implementations of the java.time classes.Most of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.Java 9 adds some minor features and fixes.Java SE 8, Java SE 9, Java SE 10, Java SE 11, and later - Part of the standard Java API with a bundled implementation.No need for strings, no need for java.sql.* classes.

Use a JDBC driver compliant with JDBC 4.2 or later. You may exchange java.time objects directly with your database. And search Stack Overflow for many examples and explanations. The Joda-Time project, now in maintenance mode, advises migration to the java.time classes. These classes supplant the troublesome old legacy date-time classes such as, Calendar, & SimpleDateFormat. The java.time framework is built into Java 8 and later. Here is example code going from an Instant or a ZonedDateTime to a. When you must use the old classes for operating with old code not yet updated for the java.time types, call the conversion methods. They are notoriously troublesome and confusing. The old /.Calendar classes are now outmoded. ( "instant: " + instant + "\nzdt: " + zdt + "\nzdtHourEarlier: " + zdtHourEarlier ) ZonedDateTime zdtHourEarlier = zdt.minus ( 1, ChronoUnit.HOURS ) ĭump to console. ZonedDateTime zdt = ZonedDateTime.ofInstant ( instant, zoneId ) ZoneId zoneId = ZoneId.of ( "America/Montreal" ) This class handles the necessary adjustments for anomalies such as Daylight Saving Time (DST). You can start with an Instant and the assign a time zone, a ZoneId object. If you care about a time zone, use the ZonedDateTime class. Note how in this instant happened to skip back to yesterday’s date. ( "instant: " + instant + " | instantHourEarlier: " + instantHourEarlier ) Instant instantHourEarlier = instant.minus ( 1, ChronoUnit.HOURS ) ĭump to console. If you only care about UTC (GMT), then use the Instant class. Java 8 and later has the new java.time framework built-in. atZone( ZoneId.of ( "America/Montreal" ) ) In UTC: Instant.now().minus( 1, ChronoUnit.HOURS )
