Use enum or subclassing to differentiate between different elements?

Question

Hello all,
I have a design decision to make.
I have two different Elements with everything the same except the name.
So I have two ideas on how this can be solved.
1. Through subclassing.
2. Through enumeration.
I have tried to make two examples of this so you can recommend 1 or 2 only on a conceptual level not implementation.
Sub classing
public class Element {
     //Methods     
public class A extends Element {
     //Nothing
public class B extends Element {
     //Nothing
public class Main {
     public static void main(String[] args) {
          Element elm = new A();
          if (elm instanceof A){}
          else if (elm instanceof B){}
}Enumeration
public class Element {
     public enum Type {A, B}
     private Type type;
     public Element(Type type) {
          this.type = type;
     public Type getType() {
          return type;
     //Methods
public class Main {
     public static void main(String[] args) {
          Element elm = new Element(Type.A);
          switch(elm.getType()) {
               case A:
               case B:

Answer 1

Thanks for the answers.
Then I will go with the enum solution that will give me a lot of free things.
Such as I can limit the API user to only choose between my predefined values and the use of my API will be much easier when used in a good IDE.
