Mar 12, 2025 · The queue uses an array with a fixed capacity, referred to as capacity, and tracks the current number of elements with a variable size. The variable front is initialized to 0 and represents the index of the first element in the array.

Arrays provide a basic yet powerful way to implement queues in Java. They give a clear insight into how data is managed within a queue, making it an excellent starting point for understanding more advanced data structures.

Feb 14, 2023 · How to Implement Queue in Java using Array and Generics? The queue is a linear data structure that follows the FIFO rule (first in first out). We can implement Queue for not only Integers but also Strings, Float, or Characters. There are 5 primary operations in Queue: Implementation: Example. "\nCreated new Float type queue q3...");

May 27, 2024 · 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.

Here, we have given a brief knowledge of the process of implementing a queue using an array. A queue is data structure that is based on first-in first-out (FIFO) in which the first item input is also the first item removed. Items are added to the end of the line and removed from the beginning.

Jan 26, 2019 · Things that we need to do while implementing a queue using an array. Decide the size of queue, that needs to be created. We can create a fixed implementation or pass the size in a constructor. Acquire that much of memory, by creating an array of that size. We need two variables to track the locations, locations to add and remove the elements.
