    I am not sure. It is not showing any errors, but I did not run. It won't compile because it depends on Ant.java which is the one with this error on EAST

    Change the code to return the correct value vs EAST.

    Suggestion: add a main() method for testing the constructor and methods. Create an instance of the Ant class, call its methods and print out the results as appropriate.

    It worked because I imported direction I suppose. That's why I don't understand. I have imported it as well in 24 and is showing error on EAST.

    Ant is not coded correctly now. That should be fixed.

    Sorry, still in EAST:

    The member enum EAST can only be defined inside a top-level class or interface

    Sorry, where does it say it is a string? I know it is not a string, where did I go wrong on syntax?

    in the Ant file you need to declare direction as an enum, i think thats you're problem

    You posted the enum definition in post#3. Did you ever use it in any of the code after that without any problems? If it did work for some classes since post #3, what has changed since then?

    There is something messed up in the way this project is configured in the IDE. I've never seen the error message that is being posted. The error message doesn't correspond to the posted source code.
    The error messages I'm familiar with look like this:
    The message should show the source with a ^ under the location of the error.
    Here is a sample from the javac compiler:
    TestSorts.java:138: cannot find symbol
    symbol  : variable var
    location: class TestSorts
             var = 2;
             ^
