Class Time

java.lang.Object
  java.util.Date
      java.sql.Time

All Implemented Interfaces:

Serializable, Cloneable, Comparable<Date>

---

public class Time
extends Date

A thin wrapper around the java.util.Date class that allows the JDBC API to identify this as an SQL TIME value. The Time class 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.

Constructor Detail

Time

@Deprecated
public Time(int hour,
                       int minute,
                       int second)

Deprecated. Use the constructor that takes a milliseconds value in place of this constructor

Constructs a Time object 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 a Time object will throw a java.lang.IllegalArgumentException.

The result is undefined if a given argument is out of bounds.

Parameters:

hour - 0 to 23

minute - 0 to 59

second - 0 to 59

---

Time

public Time(long time)

Constructs a Time object 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 Time object using a milliseconds time value.

Overrides:

setTime in class Date

Parameters:

time - milliseconds since January 1, 1970, 00:00:00 GMT; a negative number is milliseconds before January 1, 1970, 00:00:00 GMT

---

valueOf

public static Time valueOf(String s)

Converts a string in JDBC time escape format to a Time value.

Parameters:

s - time in format "hh:mm:ss"

Returns:

a corresponding Time object

---

toString

public String toString()

Formats a time in JDBC time escape format.

Overrides:

toString in class Date

Returns:

a String in hh:mm:ss format

See Also:

Date.toLocaleString(), Date.toGMTString()

---

getYear

@Deprecated
public int getYear()

Deprecated. 

This method is deprecated and should not be used because SQL TIME values do not have a year component.

Overrides:

getYear in class Date

Returns:

the year represented by this date, minus 1900.

Throws:

IllegalArgumentException - if this method is invoked

See Also:

setYear(int)

---

getMonth

@Deprecated
public int getMonth()

Deprecated. 

This method is deprecated and should not be used because SQL TIME values do not have a month component.

Overrides:

getMonth in class Date

Throws:

IllegalArgumentException - if this method is invoked

See Also:

setMonth(int)

---

getDay

@Deprecated
public int getDay()

Deprecated. 

This method is deprecated and should not be used because SQL TIME values do not have a day component.

Overrides:

getDay in class Date

Returns:

the day of the week represented by this date.

Throws:

IllegalArgumentException - if this method is invoked

See Also:

Calendar

---

getDate

@Deprecated
public int getDate()

Deprecated. 

This method is deprecated and should not be used because SQL TIME values do not have a date component.

Overrides:

Throws:

IllegalArgumentException - if this method is invoked

See Also:

setDate(int)

---

setYear

@Deprecated
public void setYear(int i)

Deprecated.

Parameters:

i - the year value.

Throws:

IllegalArgumentException - if this method is invoked

See Also:

getYear()

---

setMonth

@Deprecated
public void setMonth(int i)

Deprecated. 

This method is deprecated and should not be used because SQL TIME values do not have a month component.

Overrides:

Parameters:

i - the month value between 0-11.

Throws:

IllegalArgumentException - if this method is invoked

See Also:

getMonth()

---
