java.lang.Object
java.util.Date
java.sql.Date
- All Implemented Interfaces:
Serializable
,Cloneable
,Comparable<Date>
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.

Constructs aDate
object initialized with the given year, month, and day.The result is undefined if a given argument is out of bounds.
- Parameters:
year
- the year minus 1900; must be 0 to 8099. (Note that 8099 is 9999 minus 1900.)month
- 0 to 11day
- 1 to 31

Date
public Date(long date) Constructs aDate
object using the given milliseconds time value. If the given milliseconds value contains time information, the driver will set the time components to the time in the default time zone (the time zone of the Java virtual machine running the application) that corresponds to zero GMT.- Parameters:
date
- milliseconds since January 1, 1970, 00:00:00 GMT not to exceed the milliseconds representation for the year 8099. A negative number indicates the number of milliseconds before January 1, 1970, 00:00:00 GMT.

setTime
public void setTime(long date) Sets an existingDate
object using the given milliseconds time value. If the given milliseconds value contains time information, the driver will set the time components to the time in the default time zone (the time zone of the Java virtual machine running the application) that corresponds to zero GMT. -
