Time class in Java SQL

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

1. Time(long t): creates a Time object using a milliseconds time value.

// 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

• 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
