How to add values to an existing enums outside of the class in java

Question

How do you add more values to enums in java, I made some code to give an idea of what I'm going for but I know it doesn't work.

public class Types 
{
    public enum PieceTypes
    {}

    public void addTypes(String a)
    {
        PieceTypes = PieceTypes.values() + a;
    }

}

I have no idea where to start, please help.

The enum should be defined in compile time. yo can not change enum at run time.
You can use a List<String> or a Map<String,integer> and using simple string literals to simulate a dynamic enumeration.

Technically you _can_ add values. But you shouldn't. – Marvin Jun 10 '17 at 16:50
