There are two different classes that are used to implement the Queue interface.The Java Queue interface gives all the rules and processes of the Collection interface like inclusion, deletion, etc.It indicates that elements are entered in the queue at the end and eliminated from the front. Java Queue obeys the FIFO (First In, First Out) manner.The significant properties of the Java Queue data structure are given as follows: Java Queue is attractive because of its properties. The Java Queue can be considered as one of the most important data structures in the programming world. In Java programming language, there are two different classes which are used to implement the Queue interface. If a user wants to implement the functionality of the Queue interface in Java, then it is mandatory to have some solid classes that implement the Queue interface. Public interface Queue extends CollectionĪs we have discussed above that the Queue is an interface, therefore we can also say that the queue cannot be instantiated because interfaces cannot be instantiated. The generic representation of the Java Queue interface is shown below: It also extends the Collection interface.
The Queue is an interface in the Java that belongs to Java.util package. Components are added inside the queue from the rear end of the queue and the components are extracted from the front end of the queue. The following figure perfectly describes the FIFO (First In, First Out) property of the Java queue.Īs explained in the preceding image, we can see that the queue is a linear data structure with two terminals, i.e., start (front) and end (rear). Queue has two ends that is front and rear. There are two ends in the queue collection, i.e., front & rear. The components in a queue are stored in a FIFO (First In, First Out) behavior. In simple words, we can say that the queue is a type of data structure in the Java programming language that stores elements of the same kind. A queue is another kind of linear data structure that is used to store elements just like any other data structure but in a particular manner.
