   In order to add an element in a queue, we can use the add() method. The insertion order is not retained in the PriorityQueue. The elements are stored based on the priority order which is ascending by default. Example:

   In order to remove an element from a queue, we can use the remove() method.If there are multiple such objects, then the first occurrence of the object is removed. Apart from that, poll() method is also used to remove the head and return it. Example:

   There are multiple ways to iterate through the Queue. The most famous way is converting the queue to the array and traversing using the for loop. However, the queue also has an inbuilt iterator which can be used to iterate through the queue. Example:

   What is a queue in Java?

   • 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. The components in a queue are stored in a FIFO (First In, First Out) behavior. There are two ends in the queue collection, i.e., front & rear. Queue has two ends that is front and rear.

   What is queue data structure?

   • Queue is the fundamental data structure that follows the First-In-First-Out (FIFO) principle where the element that is inserted first is one that gets removed first. Imagine the queue of the people waiting in the line at the ticket counter: the person who arrives the first gets served first and so on.

   How to implement a queue in JavaScript?

   • This structure can resemble the physical queue of the people waiting in line. Queue can be implemented using the arrays or linked lists. In the array-based implementation, we can use the pointers front and rear to keep track of the elements. In the linked list implementation, each node contains the data elements and the reference to the next node.

   Why is Java queue attractive?

   • Java Queue is attractive because of its properties. The significant properties of the Java Queue data structure are given as follows: Java Queue obeys the FIFO (First In, First Out) manner. It indicates that elements are entered in the queue at the end and eliminated from the front.
