public class Date extends Date
A thin wrapper around a millisecond value that allows JDBC to identify this as an SQL
DATEvalue. 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.Dateinstance 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 aDateobject 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 aDateobject 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 existingDateobject 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)
Converts a string in JDBC date escape format to aDatevalue.- Parameters:
s- aStringobject representing a date in in the format "yyyy-[m]m-[d]d". The leading zero formmandddmay also be omitted.- Returns:
- a
java.sql.Dateobject representing the given date - Throws:
IllegalArgumentException- if the date given is not in the JDBC date escape format (yyyy-[m]m-[d]d)
-

valueOf
public static Date valueOf(LocalDate date)
Obtains an instance ofDatefrom aLocalDateobject with the same year, month and day of month value as the givenLocalDate.The provided
LocalDateis interpreted as the local date in the local time zone.- Parameters:
date- aLocalDateto convert- Returns:
- a
Dateobject - Throws:
