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
// 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());
}
}
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
// 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"));
}
}
Output:
Time = 21:33:09
New Time = 06:30:15
Value of 00:05:29 = 00:05:29
