Is it a good practice to use static block to initialize a shared queue
I have a class A. Its main functions are to construct data and call an addToQueue(Data data) method in Class B. Class B is to construct a persistent queue and add data to the queue. In order to make sure Class A and Class B share the same queue. I use a static block in CLass B to initialize the persistent queue and also make Class B singleton. I am not sure it is the right way or not. Any better solution to do that?
java static initialization singleton

If Class B's members are static, what's the point of making it a singleton?

@shmosel Class B also has some other methods to handle the data in the persistent queue.

If Class B is singleton then you might as well initialize the queue in the constructor of Class B rather than a static block. Also, what do you mean by Share a Queue? I'm assuming the Queue is within the boundaries of Class B and is not exposed outside.

@Bandi Kishore What I am trying to do is when other classes call Class A, Class A will get Class B instance and call the addToQueue method. I wanna make sure that Class A always get the same Class B instance and the same persistent queue.
