I have several queues that all extend a Queue class. I want to do a Queue manger base class to handle adding to the queue (and other operations).
If you take a look at the following code, I created a base class called QueueManger that has a static method called add() that will get 'Queue' and add a variable to it. I want to make getQueue() (called in add() ) abstract because I want to force other classes to provide their own implementation of the 'Queue'. The issue is I can't declare abstract static method. What is the right way to solve this?
public class RegistrationQueueManger {
@Override
Queue getQueue() {
return new RegistrationQueue(); // RegistrationQueue is a class that
// extends Queue.java
}
}
public abstract class QueueManger {
abstract static Queue getQueue(); // Error: cant do! (in java)
public static Add(String myvar) {
getQueue().add(myvar);
}
}
Note: I saw some question about this subject but it didn't really give a good answer of how to solve it and create another design to handling it.
