Processing not recognizing enum

Processing Coding Questions
1

I am trying to program an interpreter in Processing, and I’m trying to use enums. However, when I try to reference one of the values from the enum, Processing tells me that the value cannot be resolved into a variable.

I have the enum code in a java file with that general syntax, and it does seem to recognize the enum typing; however, the problem seems to lie in me trying to define a variable of that enum typing with a value from the enum.

I don’t know much about this.

processing seems to have advanced in terms of using enum

here is an example where we don’t have a java tab

public enum State {

  background(111);

  case SETUP:
    setup_2();
    break;

  case RADAR:
    radar();
    break;

  case POINTER:
    pointer();
    break;

  case HISTOGRAM:
    histogram();    
    break;

  default:
    //error 
    break;
  }
}

private void setup_2() {
  // some code here 
  _state = State.RADAR;

  stroke(0);
