/*
 * Example of remove(Object o) 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");
        /*
         * Removes the specified element from this set if it is present.
         */

        boolean isRemoved = treeSet.remove(50);
        System.out.println("isRemoved : " + isRemoved);

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

Output

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

isRemoved : true
treeSet : [10, 20, 30, 40]
