Datepublic 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 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. |
| Fields Summary |
|---|
| static final long | serialVersionUIDPrivate serial version unique ID to ensure serialization
compatibility. |
| Constructors Summary |
|---|
public Date(int year, int month, int day)Constructs a Date object initialized with the given
year, month, and day.
The result is undefined if a given argument is out of bounds.
super(year, month, day);
| public Date(long date)Constructs a Date 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.
// If the millisecond date value contains time info, mask it out.
super(date);

| Methods Summary |
|---|
| public int | getHours()This method is deprecated and should not be used because SQL Date
values do not have a time component.
throw new java.lang.IllegalArgumentException();
| | public int | getMinutes()This method is deprecated and should not be used because SQL Date
values do not have a time component.
throw new java.lang.IllegalArgumentException();
| | public int | getSeconds()This method is deprecated and should not be used because SQL Date
values do not have a time component.
throw new java.lang.IllegalArgumentException();
| | public void | setHours(int i)This method is deprecated and should not be used because SQL Date
values do not have a time component.
throw new java.lang.IllegalArgumentException();
| | public void | setMinutes(int i)This method is deprecated and should not be used because SQL Date
values do not have a time component.
throw new java.lang.IllegalArgumentException();
| | public void | setSeconds(int i)This method is deprecated and should not be used because SQL Date
values do not have a time component.
throw new java.lang.IllegalArgumentException();
| | 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 the
time in the default time zone (the time zone of the Java virtual
machine running the application) that corresponds to zero GMT.
// If the millisecond date value contains time info, mask it out.
super.setTime(date);
| | public java.lang.String | toString()Formats a date in the date escape format yyyy-mm-dd.
int year = super.getYear() + 1900;
int month = super.getMonth() + 1;
int day = super.getDate();
char buf[] = "2000-00-00".toCharArray();
buf[0] = Character.forDigit(year/1000,10);
buf[1] = Character.forDigit((year/100)%10,10);
buf[2] = Character.forDigit((year/10)%10,10);
buf[3] = Character.forDigit(year%10,10);
buf[5] = Character.forDigit(month/10,10);
buf[6] = Character.forDigit(month%10,10);
buf[8] = Character.forDigit(day/10,10);
buf[9] = Character.forDigit(day%10,10);
return new String(buf);
| | public static java.sql.Date | valueOf(java.lang.String s)Converts a string in JDBC date escape format to
a Date value.
int year;
int month;
int day;
int firstDash;
int secondDash;
if (s == null) throw new java.lang.IllegalArgumentException();
firstDash = s.indexOf('-");
secondDash = s.indexOf('-", firstDash+1);
if ((firstDash > 0) & (secondDash > 0) & (secondDash < s.length()-1)) {
year = Integer.parseInt(s.substring(0, firstDash)) - 1900;
month = Integer.parseInt(s.substring(firstDash+1, secondDash)) - 1;
day = Integer.parseInt(s.substring(secondDash+1));
} else {
throw new java.lang.IllegalArgumentException();
}
return new Date(year, month, day);
