public class Date extends 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 ajava.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.- Since:
- 1.1

Date
@Deprecated(since="1.2") public Date(int year, int month, int day)
Deprecated. instead use the constructorDate(long date)
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.
-
valueOf
public static Date valueOf(String s)
