- All Implemented Interfaces:
Serializable,Cloneable,Comparable<Date>
public class Time extends Date
A thin wrapper around the
java.util.Dateclass that allows the JDBC API to identify this as an SQLTIMEvalue. TheTimeclass adds formatting and parsing operations to support the JDBC escape syntax for time values.The date components should be set to the "zero epoch" value of January 1, 1970 and should not be accessed.

- 1.1

Time
@Deprecated(since="1.2") public Time(int hour, int minute, int second)
Constructs a
Timeobject initialized with the given values for the hour, minute, and second. The driver sets the date components to January 1, 1970. Any method that attempts to access the date components of aTimeobject will throw ajava.lang.IllegalArgumentException.The result is undefined if a given argument is out of bounds.
- Parameters:
hour- 0 to 23minute- 0 to 59second- 0 to 59
-
Time
public Time(long time)
Constructs a
Timeobject using a milliseconds time value.- Parameters:
time- milliseconds since January 1, 1970, 00:00:00 GMT; a negative number is milliseconds before January 1, 1970, 00:00:00 GMT

Method Detail
-
setTime
public void setTime(long time)
Sets a
Timeobject using a milliseconds time value.
-
valueOf
public static Time valueOf(String s)
Converts a string in JDBC time escape format to a
Timevalue.- Parameters:
s- time in format "hh:mm:ss"- Returns:
- a corresponding
Timeobject
-
toString
public String toString()
Formats a time in JDBC time escape format.
- Overrides:
toStringin classDate- Returns:
- a
Stringin hh:mm:ss format - See Also:
Date.toLocaleString(),Date.toGMTString()
-
getYear
@Deprecated(since="1.2") public int getYear()

getDayin classDate- Returns:
- the day of the week represented by this date.
- Throws:
IllegalArgumentException- if this method is invoked- See Also:
Calendar
-
getDate
@Deprecated(since="1.2") public int getDate()
Deprecated.
This method is deprecated and should not be used because SQL
TIMEvalues do not have a date component.- Overrides:

IllegalArgumentException- if this method is invoked- See Also:
getYear()
-
setMonth
@Deprecated(since="1.2") public void setMonth(int i)
Deprecated.

valueOf
public static Time valueOf(LocalTime time)
Obtains an instance of
Timefrom aLocalTimeobject with the same hour, minute and second time value as the givenLocalTime. The nanosecond field fromLocalTimeis not part of the newly createdTimeobject.- Parameters:
time- aLocalTimeto convert- Returns:
- a
Timeobject - Throws:
NullPointerException- iftimeis null- Since:
- 1.8
-
toLocalTime
public LocalTime toLocalTime()
Converts this
Timeobject to aLocalTime.The conversion creates a
LocalTimethat represents the same hour, minute, and second time value as thisTime. The nanosecondLocalTimefield will be set to zero.- Returns:
- a
LocalTimeobject representing the same time value - Since:
- 1.8
-
toInstant
public Instant toInstant()
This method always throws an UnsupportedOperationException and should not be used because SQL

toInstantin classDate- Returns:
- an instant representing the same point on the time-line as
this
Dateobject - Throws:
UnsupportedOperationException- if this method is invoked
