the element to add
Returns

Remarks
Inserts the specified element at the front of this deque 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 deque, this method is generally preferable to the #addFirst(Object) addFirst
method, which can fail to insert an element only by throwing an exception.
