TreeSetExample.java
import java.util.LinkedList;
import java.util.TreeSet;

/*
 * Example of addAll(Collection<? extends E> c) method.
 */
public class TreeSetExample
{

    public static void main(String[] args)
    {

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

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

        System.out.println("treeSet : " + treeSet + "\n");

        LinkedList<Integer> linkedList = new LinkedList<Integer>();
        linkedList.add(100);
        linkedList.add(200);

        System.out.println("linkedList : " + linkedList + "\n");

        /*
         * Adds all of the elements in the linkedList to the treeSet.
         */

        boolean isAdded = treeSet.addAll(linkedList);

        System.out.println("isAdded : " + isAdded);
        System.out.println("treeSet : " + treeSet + "\n");
    }
}
Output
treeSet : [20, 30, 40]

linkedList : [100, 200]

isAdded : true
treeSet : [20, 30, 40, 100, 200]
