public class Date

extends Date

A thin wrapper around a millisecond value that allows JDBC to identify this as a SQL DATE. 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.

Constructor Detail

Date

public Date(int year,
            int month,
            int day)

Deprecated. instead use the constructor Date(long date)

Constructs a Date object initialized with the given year, month, and day.

Parameters:

year - year-1900

month - 0 to 11

day - 1 to 31

Date

public Date(long date)

Constructs a Date object using a milliseconds time value. If the given millisecond value contains time information, the driver will set the time components to zero.

Parameters:

date - milliseconds since January 1, 1970, 00:00:00 GMT. A negative number indicates the number of milliseconds before January 1, 1970, 00:00:00 GMT.

Method Detail

setTime

public void setTime(long date)

Sets an existing Date object using the given milliseconds time value. If the given milliseconds value contains time information, the driver will set the time components to zero.

Overrides:

setTime in class Date

Parameters:

date - milliseconds since January 1, 1970, 00:00:00 GMT. A negative number indicates the number of milliseconds before January 1, 1970, 00:00:00 GMT.

valueOf

public static Date valueOf(String s)

Converts a string in JDBC date escape format to a Date value.

Parameters:

s - date in format "yyyy-mm-dd"

Returns:

a Date object representing the given date

toString

public String toString()

Formats a date in the date escape format yyyy-mm-dd.

NOTE: To specify a date format for the class SimpleDateFormat, use "yyyy.MM.dd" rather than "yyyy-mm-dd". In the context of SimpleDateFormat, "mm" indicates minutes rather than the month. For example:

 Format Pattern                         Result
  --------------                         -------
	"yyyy.MM.dd G 'at' hh:mm:ss z"    ->>  1996.07.10 AD at 15:08:56 PDT
 

Overrides:

toString in class Date

Returns:

a String in yyyy-mm-dd format
