import java.util.LinkedList;

/*
 * Example of removeAll(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);
        treeSet.add(100);
        treeSet.add(200);

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

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

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

        /*
         * Removes from this set all of its elements that are contained in the
         * specified collection
         */

        boolean isRemoved = treeSet.removeAll(linkedList);

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

Output

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

linkedList : [100, 200]

isRemoved : true
treeSet : [20, 30, 40]
