Question

Hi I have a enum array and it is a field of my class. And I am implementing clone method of this class. But I have some ideas about copying array of enums but what is the formal way of copying an enum array ?

   public enum StateEnum {
      START, PLAY, PAUSE , STOP
   }


class MyClass{
    StateEnum[] stateEnums;

    public Object clone(){
      MyClass copyClass = new MyClass();
      // copy enums
    }
}

Enum values are (or should be) immutable, so you don’t need to copy them.
You can just make a shallow copy of the array by calling System.arraycopy().
