Asynchronous execution in BlockingQueue

问题

I am using Java collections BlockingQueue for data processing. The current code looks like

while(true){
    if(queue.size() > 0)
        handle(queue.take())
}

Is there a way (in Java or other frameworks) where I can process it asynchronously, like,

queue.setHandler(new Handler<E>());

somewhere down the class..

class Handler implements IHandler<E>{
    void handle(E e){
        handle(e)
    }
}
