Below programs illustrate the working of setTime() Method of Calendar class:
Example 1:

// Java code to illustrate
// setTime() method

import java.util.*;
public class Calendar_Demo
    extends GregorianCalendar {
    public static void main(String[] args)
    {
        // Creating calendar objects
        Calendar calndr1
            = (Calendar)Calendar.getInstance();
        Calendar calndr2
            = (Calendar)Calendar.getInstance();

        // Displaying the current date
        System.out.println("The Current"
                           + " System Date: "
                           + calndr1.getTime());

        // Setting to a different date
        calndr1.set(Calendar.MONTH, 5);
        calndr1.set(Calendar.YEAR, 2006);
        calndr1.set(Calendar.DAY_OF_WEEK, 15);
        Date dt = calndr1.getTime();

        // Setting the timevalue
        calndr2.setTime(dt);

        // Displaying the new date
        System.out.println("The modified"
                           + " Date:"
                           + calndr2.getTime());
    }
}

Output:

The Current System Date: Fri Feb 22 07:33:13 UTC 2019
The modified Date:Sun Jun 18 07:33:13 UTC 2006

Example 2:

// Java code to illustrate
// setTime() method

import java.util.*;

public class Calendar_Demo
    extends GregorianCalendar {

    public static void main(String[] args)
    {
        // Creating calendar objects
        Calendar calndr1
            = (Calendar)Calendar.getInstance();
        Calendar calndr2
            = (Calendar)Calendar.getInstance();

        // Displaying the current date
        System.out.println("The Current"
                           + " System Date: "
                           + calndr1.getTime());

        // Setting to a different date
        calndr1.set(Calendar.MONTH, 10);
        calndr1.set(Calendar.YEAR, 1995);
        calndr1.set(Calendar.DAY_OF_WEEK, 20);
        Date dt = calndr1.getTime();

        // Setting the timevalue
        calndr2.setTime(dt);

        // Displaying the new date
        System.out.println("The modified"
                           + " Date: "
                           + calndr2.getTime());
    }
}

Output:

The Current System Date: Fri Feb 22 07:33:20 UTC 2019
The modified Date: Fri Nov 24 07:33:20 UTC 1995
