- A group of philosophers sat around a circular table with one chopstick between each of them in the classic dining philosophers conundrum. To eat, a philosopher need both chopsticks and always takes up the left chopstick before the right. If all of the philosophers grabbed for the left chopstick at the same moment, a stalemate may result. Implement a deadlock-free simulation of the dinner philosophers issue using threads and locks.Implement 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. Hint: Use ArrayListImplement Tower of honai in Java by using Stack. Towers Disks Smallest Largest The mission is to move all the disks to some another tower without violating the sequence of arrangement. A few rules to be followed for Tower of Hanoi are - • Only one disk can be moved among the towers at any given time. • Only the "top" disk can be removed. • No large disk can sit over a small disk.
- Write a program in the Java language that includes: 1. A class for books, taking into account the encapsulation and getter, setter. 2. Entering books by the user using Scanner 3. LinkedList class for: (Adding a new book - Inserting a book- Searching for a book using the ISBN Number - Viewing all books,delete book). 4. Serial number increases automatically with each book that is entered. 5. Printing the names of books is as follows: Serial - ISBN - Name - PubYear - Price - Notes. 6-Design a main menu that includes: • Add Book • Insert Book • Delete Book • Search . Display . Exit: In the famous dining philosophers problem, a bunch of philosophers aresitting around a circular table with one chopstick between each of them. A philosopher needs bothchopsticks to eat, and always picks up the left chopstick before the right one. A deadlock couldpotentially occur if all the philosophers reached for the left chopstick atthe same time. Using threadsand locks, implement a simulation of the dining philosophers problem that prevents deadlocksCreate a new Java class in a file named "ListPQ.java" that implements the Queue interface and uses the LinkedList provided by the JCF to implement a priority queue. Note that LinkedList does not automatically order values based on priority, so it will be up to you to make sure that values are removed in priority order. You should try to implement your priority queue as efficiently as possible - basic operations should run in constant or linear time. Your priority queue need only work with integers. Do not modify any of the provided code. //This is ArrayHeap (provided code) import java.util.Arrays; public class ArrayHeap implements Heap { private int[ ] array; private int size; public ArrayHeap() { array = new int[3]; size = 0; } @Override public void add(int value) { // add pt 1 if(size == array.length) { array = Arrays.copyOf(array, size*2); } array[size] = value; // sifting up int child = size; int parent = (child - 1) / 2; while(array[parent] > array[child]) { swap(parent,…
- 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: TITLEYEARGENREPUBLISHERWrite a Java program that prompts a user for vehicle data and stores it in a linked list, and then sorts the list in ascending order based on miles-per-gallon and writes the sorted data to a text file, you can follow these steps: Create a class named Vehicle with private fields: make (String), model (String), and milesPerGallon (double). Include getters and setters for these fields. Implement the Comparable interface for Vehicle class and override the compareTo() method to compare vehicles based on their milesPerGallon. Create a main class (for example, VehicleDriver.java) to handle user input and perform the necessary operations. Inside the main method, create a BufferedReader object for user input. Prompt the user to enter the number of vehicle data they want to enter and store it in a variable (for example, nVehicles). Use a loop to iterate nVehicles times and prompt the user to enter make, model, and miles per gallon for each vehicle. Create Vehicle objects using the input data…Write a main() method for the QuickSort class. Create a queue of Item objects and sort them in increasing order. Populate the queue with several Account/Item objects and then call the quicksort method. The Account class has the following instance variables: int accountNumber String customerName double accountBalance The Item class has the following instance variables: int itemId; String itemName double itemPrice Note: This is JAVA PROGRAMMING
- Write a JAVA program that will maintain a phone directory using a Linked-List. The program should be able to perform the following operations: Add persons details (first name, last name, phone number, city, address, sex and email) to the phone directory, where phone numbers in the directory have to be unique. (Note: each person record will store in one node in the linked-list and insert each person to the last) Delete any person details by a given phone number. Update telephone number by providing person first name. Display all details of persons from a phone directory. Search telephone number based on person first name. (Note: use sequential search to find all telephones for the given first name) Sort all persons in the phone directory ascending based on person first name. (Note: use bubble or selection sort to arrange the entire phone directory)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.Implement the Round Robin Scheduler as described in attached notes “Round Robin SchedulerExample.pdf” using queue (you can use either ArrayQueue or LinkedQueue), based on theprovided starter Python code “robin_scheduler.py”. In the starter file, three tasks have alreadybeen set in a tasks list according to the example in the attached document. You are only asked tocomplete the method “scheduling”. Once you finish your code based on the starter code and runit, the output should be same as bellow. You should test your code using more examples.
