java.util.concurrent.BlockingQueue.offer()
Inserts the specified element into this queue if it is possible to do so immediately without violating capacity restrictions, returning {@code true} upon success and {@code false} if no space is currentlyavailable. When using a capacity-restricted queue, this method is generally preferable to {@link #add}, which can fail to insert an element only by throwing an exception. @param e the element to add @return {@code true} if the element was added to this queue, else{@code false} @throws ClassCastException if the class of the specified elementprevents it from being added to this queue @throws NullPointerException if the specified element is null @throws IllegalArgumentException if some property of the specifiedelement prevents it from being added to this queue
