![]() ![]() The addition can only be performed when the queue is not full i.e rear =0. The new element is added at the back of the queue. Enqueue operation : This indicates addition of a new element to the queue.Initially the head and rear both variables will be initialized to -1 indicating that the queue is empty. And the rear pointer will point to the last element in the array or in other words, it will store the index position of the last element stored in the array. The front pointer will point to the first element in the array or in other words, it will store the index position of the first element in the array. Maintain two variables as pointers i.e front and rear. ![]() To implement a queue using an array, create an array of size N. It performs these operations in FIFO i.e First In First Out manner. In a queue data structure the insertion and deletion is performed at the back and at the front of the queue respectively. Knowledge of Java, basic data structures, working of array and understanding of time and space complexity.Ĭheck interface in Java to know about the operations that can be performed on the queue. It also discusses the time and space complexity of the code implemented, problems with the current approach and the solution for the same. This post provides queue implementation using an array, a diagrammatic representation of queue using array, code implementation. In the previous post I discussed about interface in Java and the operations that can be performed on it. ![]()
