TreeSet clone Example
TreeSet class clone example. This example shows you how to use clone method.
TreeSet class clone example.public Object clone() Returns a shallow copy of this TreeSet instance. (The elements themselves are not cloned.)
Here is the code
/**
* @ # Clone.java
* A class repersenting use to clone method
* of TreeSet class in java.util package
* version 23 May 2008
* author Rose India
*/
import java.util.*;
public class Clone {
public static void main(String[] args) {
// Create new TreeSet objects:
TreeSet treeset1 = new TreeSet();
TreeSet treeset2 = new TreeSet();
// Create new element objects and add object objects:
treeset1.add(new Integer(1));
treeset1.add(new Integer(2));
treeset1.add(new Integer(3));
System.out.println("treeset1 = " + treeset1);
//Create clone and display
treeset2 = (TreeSet) treeset1.clone();
System.out.println("treeset2 = " + treeset2);
}
} |
Output
treeset1 = [1, 2, 3]
treeset2 = [1, 2, 3] |
