Best way to return status flag and message from a method in Java

try {
    AuthenticateMethod();
} catch (AuthenticateError ae) {
    // Display ae.getMessage() to user..
    System.out.println(ae.getMessage());
    //ae.printStackTrace();
}

class Tuple<L, R> {

    public final L left;
    public final R right;

    public Tuple( L left, R right) {
    	this.left = left;
    	this.right = right;
    }
}

public Option<String> authenticate(String arg) {
   if (success(arg))
      return Option.some("Just an example");
   else
      return Option.none();
}


...


for(String s : authenticate(secret)) {
   privilegedMethod();
}

public Either<Fail, String> authenticate(String arg) {
   if (success(arg))
      return Either.right("Just an example");
   else
      return Either.left(Fail.authenticationFailure());
}


...


Either<Fail, String> auth = authenticate(secret);
for(String s : auth.rightProjection()) {
   privilegedMethod();
}
for(Fail f : auth.leftProjection()) {
   System.out.println("FAIL");
}

class SomeClass {
public int authenticate (Client client) {
//returns 0 if success otherwise one value per possible failure
}
public String getAuthenticationResultMessage (int authenticateResult) {}
//returns message associated to authenticateResult
}

if (authenticate()) {
  // normal behaviour...
}
else {
  // error case...
}

authenticate();
// normal behaviour...

if (isAuthenticated()) {
//...
}

	if (sb == null)
		throw new IllegalArgumentException();

	}
}

public static void main(String[] args)
