Wite in java. Dont plagirize. Add comments. Keep code neat. Need this by today.
Use stacks from the STL to implement a video game library functionality. In this implementation, consider a VideoGame class with title, release year, genre and publisher as variables. Provide setters and getters to these variables.
In main, create a stack of video games. Add 5 different game objects into the stack. Then in a loop, for each item that you retrieve from the stack display the game information as follows:

I'm developing a card game that requires one deck of 52 cards using Java. The 52 card has 4 suits from top to bottom: diamonds (d), clubs (c), hearts (h), and spades (s). Each card has a point.
From the code I've given, I want the program to perform the same but using comparator/comparable instead of hashmaps.
The rest of the instructions are in the images just for reference purposes.

- The implementation of a queue in an array, as given in this chapter, uses the variable count to determine whether the queue is empty or full. You can also use the variable count to return the number of elements in the queue. On the other hand, class linkedQueueType does not use such a variable to keep track of the number of elements in the queue. Redefine the class linkedQueueType by adding the variable count to keep track of the number of elements in the queue. Modify the definitions of the functions addQueue and deleteQueue as necessary. Add the function queueCount to return the number of elements in the queue. Also, write a program to test various operations of the class you defined.arrow_forwardCode using javaarrow_forwardImplement a simple stack in java using the scenario below. A company wishes to keep track of the order in which it employed staff. Users can enter either "f" to fire, "h" to hire or "e" to end the program. When a member of staff is employed, their employee number is added to the top of a stack when someone has to be made redundant, the last person to join the company is removed from the top of the stack.

- Need help with this in Java Implement a “To Do” list. Tasks have a priority between 1 and 9, and a description (which you can come up with on your own, say, “wash dishes”). The program is going to prompt the user to enter the tasks by running the method add_priority_description, the program adds a new task and prints the current list with priority 1 tasks on the top, and priority 9 tasks at the bottom. The program will continue to ask the user if they want to add another tasks, and repeat the add_priority_description method, or enters Q to run the quit method to quit the program. Sample output (not limited to) 1. Study for the final 1. Take the final 2. Watch Justice League with friends 3. Play ball 9. Wash Dishes 9. Clean room. There is a possibility of two tasks having the same priority. If so, the last task that was entered gets to be printed first. Use HEAP in your solution. (Java)arrow_forwardGiven a singly linked list, reverse the list. This means you have to reverse every node. For example if there are 4 nodes, the node at position 0 will move to position 3, the node at 1 will move to position 2 and so on. You do not have to write the Node class just write what you have been asked to. You are NOT allowed to create a new list. In python languagearrow_forwardImplement a “To Do” list.

This project provides practice for that type of work.The given program, shown below, implements a circular-array queue. A queue is a British term for aline of people waiting to be served. A queue can also refer to any line of items where the item at thefront of the queue is served next, and new items are added at the rear of the queue. Informationtransmission systems, like the Internet, have lots of queues, where messages in transit are temporarilystalled at some intermediate system node, waiting to get into the next available time slot on the next legof their journey. A queue’s length is the total number of people or items currently waiting. When thenext item is served, that shortens the queue by one. When another person arrives, that lengthens thequeue by one. A queue’s capacity is the maximum number of items that can fit in the line at one time.If…arrow_forward

You should keep track of the due date. Your program should 1. Add a new assignment. 2. Remove an assignment. 3. Provide a list of the assignments in the order they were assigned. 4. Find the assignment(s) with the earliest due date.arrow_forwardWrite the program in python MythicalWorld is divided up into four different zones. In each zone there are three different pods of mythical beings. You are given two lists of the same length as follows:mythicalPods = ["Fairies", "Elves", "Cyclops", "Unicorns", "Kelpie", "Dragons", "Centaurs", "Sea Serpents", "Werewolf", "Sprites", "Loch Ness Monsters", "Manticore"] mythicalZones = [3, 3, 4, 2, 1, 4, 2, 1, 4, 3, 1, 2] The list of zones contains the zone of each pod in the order as given in the pods list. For example, Fairies live in zone 3, Elves live in zone 3, Cyclops live in zone 4, etc. Given these two lists, sort the lists first based on the different zones (in ascending order) and then within each zone by the pod names (in ascending alphabetic order), by implementing the following two functions: function sortByZones that, given the lists, sorts the two lists based on the numeric order of the zones of the mythical pods (the mythical pods can be within any order in each zone…arrow_forwardIt is a Java programarrow_forward
