Problem with switch

Question

Hi,
I have a problem using switch statement.
I have a class named Resources in which I declare all the final variables.
I have created an instance of Resources named res in the main class.
But I cannot use the final variables in the main class in the following way:
switch (a) {            //a is int
   case res.LEFT:       //LEFT is a final int variable in Resources     //PROBLEM
      //do something
   break;
}The compiler complained: Constant expression required
What is the matter?
Thank you.

Here is how the Resources class looks like:
public class Resources {
  public final int LEFT = 0, RIGHT = 1;
}In my main class, I just used the following to create the object:
private Resources res = new Resources();
