Is it possible to add or modify element at the head of linked blocking queue?

Or maybe will be better to use other class for synchronized access to data?

Not sure if I understood your question correctly, but LinkedBlockingDeque provides both FIFO and LIFO operations (similar to a Stack). Maybe it does what you want.

You can modify the element at the head of a linked blocking queue (use peek() to obtain it. If you want to add elements to the head of a data structure then use a LinkedBlockingDeque instead.

Use LinkedBlockingDeque if you want to manipulate both ends of a queue.
