Time class is a part of Java SQL package.This class is a thin wrapper around java.util.Date that allows JDBC API to identify this as a SQL TIME value. The initial value of time is set to 1st January, 1970. All values of time after that is positive and time before that is negative.
Class Hierarchy:
java.lang.Object ↳ java.util.Date ↳ java.sql.Time
Constructors:
- Time(long t): creates a Time object using a milliseconds time value.
Example to demonstrate how to create object of Time Class using Constructor:
// Java program to demonstrate // Constructor of Time Class import java.sql.*;
class GFG {
public static void main(String args[])
{
// time in milliseconds
long milli = 123456789999l;
// create a object
java.sql.Time time = new java.sql.Time(milli);
// display the time
System.out.println( "Time = " + time.toString());
}
} |
Time = 21:33:09
Methods:
Method | Explanation |
---|---|
setTime(long t) | sets the value of time using milliseconds |
toString() | Formats a time in JDBC time escape format. |
valueOf(String s) | Converts a string in JDBC time escape format to a Time value. |
-
setTime(long time): This method sets a Time object using a milliseconds time value.
Syntax:
public void setTime(long time)
Parameters: This method accepts a mandatory parameter time which represents the time to be set in milliseconds since January 1, 1970, 00:00:00 GMT.
-
valueOf(String s): This method converts a string in JDBC time escape format to a Time value.
Syntax:
public static Time valueOf(String s)
Parameters: This method accepts a mandatory parameter s which represents the time in format “hh:mm:ss”
Return Value: This method returns a corresponding Time object
-
toString(): This method formats a time in JDBC time escape format.
Syntax:
public String toString()
Return Value: This method returns a String in hh:mm:ss format.
Program to demonstrate setTime(), valueOf() and toString() methods:
// Java program to demonstrate // setTime(), valueOf() and toString() methods: import java.sql.*;
class GFG {
public static void main(String args[])
{
// time in milliseconds
long milli = 123456789999l;
// create a object
java.sql.Time time = new java.sql.Time(milli);
// display the time
System.out.println( "Time = " + time.toString());
// ----- setTime() -----
// set another time
// using setTime() method
long milSec = 455415454l;
time.setTime(milSec);
// ----- toString() -----
// display the time
// using toString() method
System.out.println( "New Time = " + time.toString());
// ----- valueOf() -----
// using valueOf() method
System.out.println( "Value of 00:05:29 = "
+ Time.valueOf( "00:05:29" ));
}
} |
Time = 21:33:09 New Time = 06:30:15 Value of 00:05:29 = 00:05:29
