Java SQL Timestamp setTime() function with examples

The setTime() function is a part of Timestamp class of Java SQL.The function is used to set the time of the Timestamp object. The function takes time in milliseconds which represents the time in milliseconds after 1st January, 1970.

Function Signature:

public void setTime(long t)

Syntax:

ts1.setTime(l);

Parameters: The function accepts a long value l as parameter which is to be set as the time.

Return value: The function does not return any value.

Exception: The function does not throw any exceptions.

Below programs illustrates the use of setTime() function

Example 1: Create a timestamp and use the setTime() to change the time of timestamp object.

// Java program to demonstrate the
// use of setTime() function

import java.sql.*;

public class solution {
    public static void main(String args[])
    {
        // Create two timestamp objects
        Timestamp ts = new Timestamp(10000);

        // Display the timestamp object
        System.out.println("Timestamp time: "
                           + ts.toString());

        // Set the value of timestamp object
        // using setTime function
        ts.setTime(1000000000);

        // Display the new timestamp object
        System.out.println("New Timestamp time: "
                           + ts.toString());
    }
}

Output:

Timestamp time: 1970-01-01 00:00:10.0
New Timestamp time: 1970-01-12 13:46:40.0

Example 2: Create a timestamp and use the setTime() to change the time of timestamp object by passing negative long value as parameter. Giving negative long value represents the time before 1st January 1970

// Java program to demonstrate the
// use of setTime() function

import java.sql.*;

public class solution {
    public static void main(String args[])
    {
        // Create two timestamp objects
        Timestamp ts = new Timestamp(10000);

        // Display the timestamp object
        System.out.println("Timestamp time: "
                           + ts.toString());

        // Set the value of timestamp object
        // using setTime function
        ts.setTime(-1000000000);

        // Display the new timestamp object
        System.out.println("New Timestamp time: "
                           + ts.toString());
    }
}

Output:

Timestamp time: 1970-01-01 00:00:10.0
New Timestamp time: 1969-12-20 10:13:20.0
