enum (310-065)

[Santiago Ennis]

Zone.java

  
package constant;

public enum Zone {  // top-level enum cannot be private or protected
	NORTH, EAST, WEST, SOUTH // semicolon NOT required, when there are only enum constants
}

TestState.java

package constant.clazz;

import constant.Zone;

class State {
	private String name;
	private Zone zone;
	
	State(String name, Zone zone) {
			this.name = name;
			this.zone = zone;
		}
	
	// public static final StateZone DEFAULT_STATE_ZONE = StateZone.NORTH; // Compilation Fails!
	public static final City.StateZone DEFAULT_STATE_ZONE = City.StateZone.NORTH;
	
	static class City {
		private String name;
		private StateZone zone;
		
		public static final StateZone DEFAULT_STATE_ZONE = StateZone.NORTH;
		
		City(String name, StateZone zone) {
			this.name = name;
			this.zone = zone;
		}
		
		protected enum StateZone {
			NORTH, EAST, WEST, SOUTH
		}
	}
}

public class TestState {
	public static void main(String[] args) {
		State gujarat = new State("Gujarat", Zone.NORTH);
		City baroda = new City("Baroda", State.City.StateZone.NORTH); // Yike! Compile Error!! WHY?
	}
}

Compilation Error:
cannot find symbol symbol : constructor City(java.lang.String,constant.clazz.State.City.StateZone)
location: class constant.clazz.City
City baroda = new City("Baroda", State.City.StateZone.NORTH);
1 error

Why is there a compile-time error? How do I resolve it?

change it to

 State.City baroda = new State.City("Baroda", State.City.StateZone.NORTH);
