the method can only set one of public / protected / private

Question

I'm implementing an interface:

public interface Consultant {
    // some documentation here explaining it should throw 3 types of exceptions
    CellLocation suggest(GameBoard gameBoard);
}

It uses another interface:

public interface GameBoard {
    CellState getCellState(CellLocation cellLocation);
}

I wrote a lot of methods, but just started implementing the all-important suggest method. It looks like this so far:

public class YourConsultant implements Consultant {
    @Override
    public CellLocation suggest(GameBoard gameBoard) {
        char[][] arrayBoardGlobal;
        Player currentPlayerGlobal;
        GameState gameStateGlobal;
        return null;
    }
}

But I get the error

The method suggest in type YourConsultant can only set one of public / protected / private

Of course I cannot change it from public to anything else because of the interface.

What could be the cause? I haven't found the answer here or the net, probably because it brings up basic info about access modifiers. I'm using Eclipse Neon.

Answer 1

Okay, I found the error... I left a lonely "private" tag hanging in the air a few lines before YourConsultant :D. Your comments were helpful, especially the one asking for a Minimal, Complete and Verifiable example
