Below programs illustrate the java.util.GregorianCalendar.clone() method:
Program 1:
// Java Program to illustrate GregorianCalendar.clone()// function import java.io.*;import java.util.*; class GFG { public static void main(String[] args) { // Creating a new calendar GregorianCalendar cal = (GregorianCalendar) GregorianCalendar.getInstance(); // Display the date and time System.out.println("Date and Time in" +" cal object : "+ cal.getTime()); GregorianCalendar newcalender = new GregorianCalendar(); // Cloning the object newcalender = (GregorianCalendar)cal.clone(); // Display date and time System.out.println("Date and Time in"+ " newcalender object : "+ newcalender.getTime()); }} |
Output:
Date and Time in cal object : Fri Aug 03 11:01:24 UTC 2018 Date and Time in newcalender object : Fri Aug 03 11:01:24 UTC 2018
Program 2:
// Java Program to illustrate // GregorianCalendar.clone()// function import java.io.*;import java.util.*; class GFG { public static void main(String[] args) { // Creating a new calendar GregorianCalendar cal1, cal2; cal1 = (GregorianCalendar)GregorianCalendar. getInstance(); // Display the current date and time System.out.println("Current Date and Time : " + cal1.getTime()); // Modifying the current date and time cal1.add((GregorianCalendar.MONTH), 2); // Cloning the object cal2 = (GregorianCalendar)cal1.clone(); // Display date and time System.out.println("New Date and Time : " + cal2.getTime()); }} |
Output:
Current Date and Time : Fri Aug 03 11:01:27 UTC 2018 New Date and Time : Wed Oct 03 11:01:27 UTC 2018
