What SimpleDateFormat to use for parsing Oracle date ?
I'm using this SimpleDateFormat.
SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy/mm/dd hh:mm:ss.sss");
its giving this exception.
java.text.ParseException: Unparseable date: "2011-08-19 06:11:03.0"
Kindly please tell me the SimpleDateFormat to use. Thanks.
You should use this Pattern "yyyy-MM-dd HH:mm:ss.S"
instead of "yyyy/mm/dd hh:mm:ss.sss"
.
little h
for "Hour in am/pm (1-12)" and H
for "Hour in day (0-23)"
see here: SimpleDateFormat
SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss.S");
Date date = dateFormat.parse("2011-08-19 06:11:03.0");
LocalDateTime.parse(
"2011-08-19 06:11:03.0".replace( " " , "T" )
)
Your input string does not match your formatting pattern. Your pattern has slash characters where your data has hyphens.
Furthermore, you are using terrible old date-time classes that are now legacy, supplanted by the java.time classes.
Your input string nearly complies with the ISO 8601 standard for date-time formats. Replace the SPACE in the middle with a T
.
String input = "2011-08-19 06:11:03.0".replace( " " , "T" ) ;
Your input lacks any indicator of time zone or offset-from-UTC. So we parse as a LocalDateTime
, for an object lacking any concept of zone/offset.
LocalDateTime ldt = LocalDateTime.parse( input ) ;
To generate a string in standard format, call toString
.
String output = ldt.toString() ;
If this input was intended for a specific time zone, assign it.
ZoneId z = ZoneId.of( "Africa/Tunis" ) ;
ZonedDateTime zdt = ldt.atZone( z ) ;
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 .
With a JDBC driver complying with JDBC 4.2 or later, you may exchange java.time objects directly with your database. No need for strings or java.sql.* classes.
Where to obtain the java.time classes?
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 .
