import java.util.Arrays;
import java.util.LinkedHashSet;

public class Main {
  public static void main(String[] args) {

    LinkedHashSet linkedHashSet = new LinkedHashSet();

    linkedHashSet.add("1");
    linkedHashSet.add("2");
    linkedHashSet.add("java2s.com");

    Object[] objArray = linkedHashSet.toArray();
    System.out.println(Arrays.toString(objArray));
  }
}

The output:
