TreeSetExample.java

import java.util.TreeSet;

/*
 * Example of clone() method.
 */
public class TreeSetExample
{
    public static void main( String[] args )
    {

        TreeSet<Integer> treeSet = new TreeSet<Integer>();

        treeSet.add(10);
        treeSet.add(50);
        treeSet.add(40);
        treeSet.add(20);
        treeSet.add(30);

        System.out.println("treeSet : " + treeSet + "\n");
        /*
         * Returns a shallow copy of this TreeSet instance. (The elements
         * themselves are not cloned.)
         */
        TreeSet<String> clonedTreeSet = (TreeSet<String>) treeSet.clone();

        System.out.println("clonedTreeSet : " + clonedTreeSet);

    }
}

Output

treeSet : [10, 20, 30, 40, 50]

clonedTreeSet : [10, 20, 30, 40, 50]
