![]() ![]() offer(): The offer() method is preferable to the add() method, as it inserts the specified element into the queue without violating any capacity restrictions.The method is inherited from the Collection interface. add(): The add() method is used to insert elements at the end, or at the tail of the queue.Let us take a lok at some important Java Queue methods, Methods In Java Queue Since these implementations are not thread safe, PriorityBlockingQueue acts as an alternative for thread safe implementation.Įxample: Queue q1 = new LinkedList() Queue q2 = new PriorityQueue() Following are the few implementations that can be used: In order to use the queue interface, we need to instantiate a concrete class. Let us move to the next topic of this article on Java Queue, Implementation Of Java Queue Deques support insertion and deletion of elements at both the ends. The queues available in are known as Unbounded Queues, while the queues present in the package are known are Bounded Queues.Īll queues, except the Deques, support insertion at the end and deletion from the front. Queue supports multiple methods, including insertion and deletion. This interface is available in the and extends the Collection Interface. the elements are inserted at the end of the list, and are deleted from the beginning of the list. ![]() These are the pointers this article focus on,Ī queue is a data structure which follows the principle of FIFO (First-In-First-Out) i.e. In this article we will take a look at one such data structure that is Java Queue. Java is a powerful programming language and it supports various data structures to make the life of programmers easy. ![]()
