What is the difference between sql.Date and util.Date

Please don't tell sql date is a sub-class of util.Date

[Paul Sturrock]

java.sql.Date exists to wrap the ANSI SQL DATE datatype. See the JavaDocs for more.

[rama murthy]

could you please throw more light on this topic.

java.sql.Date dosen't store millisecond information while java.util.Date does.

Thanks srini.

But even sql.Date is having a constructor that takes milli seconds right?

I didn't fully understand your answer.

From javadoc link in one of the responses:

A thin wrapper around a millisecond value that allows JDBC to identify this as an SQL DATE value. A milliseconds value represents the number of milliseconds that have passed since January 1, 1970 00:00:00.000 GMT.

To conform with the definition of SQL DATE, the millisecond values wrapped by a java.sql.Date instance must be 'normalized' by setting the hours, minutes, seconds, and milliseconds to zero in the particular time zone with which the instance is associated.
