Inserts the specified element into this queue if it is possible to do so immediately without violating capacity restrictions, returning true upon success and false if no space is currently available. 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 true if the element was added to this queue, elsefalse @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
