Instead, use java.time
As others stated:
- This class inheritance is poor design, a flawed hack.
- Now moot, as this class is now legacy, supplanted by
java.time.Instant
.
Avoid all the old legacy date-time classes found outside the java.time package.
For databases, use a driver compliant with JDBC 4.2 or later to directly exchange java.time objects with your database. You can forget all about java.sql.Timestamp
.
Storing:
Instant instant = Instant.now() ;
myPreparedStatement.setObject( … , instant ) ;
Retrieving:
Instant instant = myResultSet.getObject( … , Instant.class ) ;
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.
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.
