Below programs illustrate the use of clone() Method:
Example 1:
Java
// Java code to demonstrate // clone() method of Date class import 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()); } } |
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 class import 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()); } } |
Original Date: Wed Jan 30 05:39:10 UTC 2019 Cloned Date: Wed Jan 30 05:39:10 UTC 2019
