Each node in a linked list includes links to other nodes. That's why LinkedList requires more storage than ArrayDeque. Early in Java, inheritance was overused IMO - Properties being another example. For me, the crucial word in the docs you quoted is consistent . Deque exposes a set of operations which is all about being able to fetch/add/remove items from the start or end of a collection, iterate etc - and that's it. Deque Interface. The interface java.util.Deque (→ JavaDoc) inherits from java.util.Queue and extends it with methods to append elements at the front of the deque, remove elements from the back of the deque, and view the element at the back of the deque without removing it.

Deque implementations generally do not define element-based versions of the equals and hashCode methods, but instead inherit the identity-based versions from class Object. This interface is a member of the Java Collections Framework. Since: 1.6; Method Summary. Methods ; Modifier and Type 29 rows This is so because null is used as a special return value by various methods to indicate that the deque is empty. Deque implementations generally do not define element-based versions of the equals and hashCode methods, but instead inherit the identity-based versions from class Object. This interface is a member of the Java Collections Framework.

Deque data structure. A Deque is a generalized queue structure that permits insertion and removal of elements at both ends where as in queue element can only be added at one end and removed from the other end. Standard Deque in Java. You can load any object into a Java Deque by default. Using Java Generics, however, you can restrict the types of objects that you can inject into a Deque. Take an example here.

Deque extends Queue Interface. Deque supports element insertion and removal from both the ends. Why Deque?

Deque < MyObject > deque = new LinkedList); Now this Deque may only have instances 1. The Java Deque Interface. The Java Deque (Double-Ended-Queue) interface extends the Queue interface and Java’s LinkedList implements Deque interface. In the past coding examples, we used the LinkedList as queue via the Java Queue Interface. In this example, we will use our LinkedList using the Deque Interface.
