        /*
         * Inserts the specified element at the end of this deque if it is
         * possible to do so immediately without violating capacity
         * restrictions. When using a capacity-restricted deque, it is generally
         * preferable to use method offerLast(E).

        System.out.println("deque : " + deque + "\n");

        /*
         * Inserts the specified element at the end of this deque unless it
         * would violate capacity restrictions. When using a capacity-restricted
         * deque, this method is generally preferable to the addLast(E) method,
         * which can fail to insert an element only by throwing an exception.
         */
        boolean isAdded = deque.offerLast(10);
        System.out.println("isAdded : " + isAdded);
        System.out.println("deque : " + deque);

    }
}

Output

deque : [100, 200, 300]

deque : [100, 200, 300, 50]

isAdded : true
deque : [100, 200, 300, 50, 10]
