/*
 * Example of toArray(T[] a) 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(10);
        treeSet.add(50);

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

        Integer[] integerArray = new Integer[treeSet.size()];

        /*
         * treeSet elements will be copied to integerArray
         */

        treeSet.toArray(integerArray);

        for( Integer value : integerArray )
        {
            System.out.println(value);
        }
    }
}
Output
treeSet : [10, 20, 30, 40, 50]
