Syntax:
public Object clone()
Parameters: The method does not accept any parameters.
Return Value: The method returns a clone of the object.
Below programs illustrate the use of clone() Method:
Example 1:
Java
// Java code to demonstrate// clone() method of Date classimport java.util.Date;import java.util.Calendar;public class GfG { public static void main(String args[]) { // Creating a Calendar object Calendar c1 = Calendar.getInstance(); // Set Month // MONTH starts with 0 i.e. ( 0 - Jan) c1.set(Calendar.MONTH, 11); // Set Date c1.set(Calendar.DATE, 05); // Set Year c1.set(Calendar.YEAR, 1996); // Creating a date object // with specified time. Date dateOne = c1.getTime(); Object dateTwo = dateOne.clone(); System.out.println("Original Date: " + dateOne.toString()); System.out.println("Cloned Date: " + dateTwo.toString()); }} |
Output:
Original Date: Thu Dec 05 05:39:04 UTC 1996 Cloned Date: Thu Dec 05 05:39:04 UTC 1996
Example 2:
Java
// Java code to demonstrate// clone() method of Date classimport java.util.Date;import java.util.Calendar;public class GfG { public static void main(String args[]) { // Creating a Calendar object Calendar c1 = Calendar.getInstance(); // Set Month // MONTH starts with 0 i.e. ( 0 - Jan) c1.set(Calendar.MONTH, 00); // Set Date c1.set(Calendar.DATE, 30); // Set Year c1.set(Calendar.YEAR, 2019); // Creating a date object // with specified time. Date dateOne = c1.getTime(); Object dateTwo = dateOne.clone(); System.out.println("Original Date: " + dateOne.toString()); System.out.println("Cloned Date: " + dateTwo.toString()); }} |
Output:
Original Date: Wed Jan 30 05:39:10 UTC 2019 Cloned Date: Wed Jan 30 05:39:10 UTC 2019
