    public static void main(String[] args)
    {

        dateOne.setTime(1000);

        // Prints the time
        System.out.println("Date after setting"
                           + " the time: "

Program 2:

// Java code to demonstrate
// setTime() function of Date class

import java.util.Date;
import java.util.Calendar;
public class GfG {
    // main method
    public static void main(String[] args)
    {

        // creating a Calendar object
        Calendar c1 = Calendar.getInstance();

        // set Month
        // MONTH starts with 0 i.e. ( 0 - Jan)

        // set Year
        c1.set(Calendar.YEAR, 1996);

        // creating a date object with specified time.
        Date dateOne = c1.getTime();

        System.out.println("Date initially: "
                           + dateOne);

        // Sets the time
        dateOne.setTime(1000999);

        // Prints the time
        System.out.println("Date after setting"
                           + " the time: "
