Using Java enums from different classes?
public class Test
{
    // ...
    public enum Status {
        Opened,
        Closed,
        Waiting
    }
    // ...
}

public class UsingEnums
{
    public static void Main(String[] args)
    {
        Test test = new Test(); // new Test object (storing enum)

        switch(test.getStatus()) // returns the current status
        {
            case Status.Opened:
                // do something
            // break and other cases
        }
    }
}

switch(test.getStatus()) // returns the current status
{
    case Opened:
        // do something
        // break and other cases
}

Test test = new Test(); // new Test object (storing enum)

    switch(test.getStatus()) // returns the current status
    {
        case Test.Status.Opened:
            // do something
        // break and other cases
    }

case Opened:

case Test.Status.Opened:

an enum switch case label must be the unqualified name of an enumeration constant
