Question

This is probably a stupid question, but I can’t seem to do it. I want to set up some enums in one class like this:

public enum Direction { north, east, south, west };

Then have that enum type accessible to all classes so that some other class could for instance have:

Direction dir = north;

and be able to pass the enum type between classes:

public void changeDirection(Direction direction) {
   dir = direction;
}

I thought that setting the enum to public would make this automatically possible, but it doesn’t seem to be visible outside of the class I declared the enum in.

Answer 1

You can do one of two things.

1- Move the declaration of the enum outside of the class

Today you probably have something like this

public class ClassName
{
  public enum Direction
  {
    north, south, east, west
  }
  // ... Other class members etc.
}

Which will change to

public class ClassName
{      
  // ... Other class members etc.
}

// Enum declared outside of the class
public enum Direction
{
  north, south, east, west
}

2- Reference the enum using the class name

ClassName.Direction.north

Eg.

public void changeDirection(ClassName.Direction direction) { 
   dir = direction; 
}

Where ClassName is the name of the class that you declared the enum in.
