Project 2
Use Netbeans, to write a simple java program using the following data structures:
1. Stack by Linked List2. Circular Queue by Array
The program should implement the following functions:
1. Insert2. Read/Print3. Remove an item4. Delete (the entire list)
On the initial start of the program, users should be prompted for at least five elements into the list. After which they should be presented with options that will allow them to perform the functions defined above. Note that exception handling must be implemented.
Screenshots of the cods as proof of its implementation should be included
Q/ In java language

A.You can dequeue an element from the queue
B.The size of the queue is 1
C.You cannot enqueue an element into the queue.

- alfa D14:18 PM + Project PM.pdf Requirements In this project, you will implement one class: 1. Dynamic Queue: DynamicQueue. A queue stores objects in an ordered list and allows insertions at one end and deletions from the other end of the list. The objects in this queue are stored in an array. The capacity of the array may be changed depending on the number of objects currently stored in the array, according to the following two rules: If an object is being inserted into the array is doubled. • If, after removing an object from a queue where the number of objects is one-quarter (1/4) the capacity of the array, then the capacity of the array is halved. The capacity of the array may not be reduced below the initially specified capacity. queue where the array is already full, the capacity of Description The aim of this project is to develop a dynamic queue. You will implement a queue using an array. The capacity of the array may be changed dynamically after insertions or deletions.

The class should have the following methods: Enqueue(int value) - adds a new element to the end of the queue Dequeue() - removes the element from the front of the queue and returns it Peek() - returns the element from the front of the queue without removing it Count() - returns the number of elements in the queue The class should also have a property named "IsEmpty" that returns a boolean indicating whether the queue is empty or not. Constraints: The queue should be implemented using an array and the array should automatically resize when needed. All methods and properties should have a time complexity of O(1) You can write the program in C# and use the test cases to check if your implementation is correct. An example of how the class should be used: Queue myQueue = new Queue(); myQueue.Enqueue(1); myQueue.Enqueue(2); myQueue.Enqueue(3); Console.WriteLine(myQueue.Peek()); // 1…arrow_forwardAssume you have a queue with a maximum size of 100 elements and you want to perform the following operations: Enqueue 50 elements into the queue.

What is the final size of the queue after performing all these operations?arrow_forward
