- JAVA You are requested to implement a “message buffer and response connector” class using Javaprogramming language. The following figure depicts a message buffer and response connectorclass, followed by detailed operations specifications. The message buffer and response connectorclass has three operations, send(), receive(), and reply().Your program should create two separate threads for testing your implementation, a producerthread, and a consumer thread. The producer thread sends a message having a structure (string,integer) – e.g., (add, 3) or (multiply, 7) - to a consumer thread via a message buffer and responseconnector. The consumer thread encapsulates a SimpleCalculation class that has two operations,add() and “multiply(). You should implement the SimpleCalculation class as well. When theconsumer thread receives a message from the connector, it extracts the message and then callsone of the operations on the SimpleCalculation class, depending on the message. For example,the…For programming tasks, we can use an Array or an Array List. Describe when using an Array would be a good choice, and Describe when using an Array List would be a better choice. You must start a thread before you can read and reply to other threadsImplement a solution to the critical section problem with threads using semaphores. you must add a third counting thread which counts by 1 each time it enters its critical section to 3,000,000. Each counts to 3,000,000 for a total of 9,000,000.
- An auction is being conducted for a valuable item of price Rs.10,000. There are three persons participating in the auction (three threads). Each person has only one chance to bid. If he tries to bid again, he has to wait until all the other threads are given a chance. Synchronize the events to organize the auction. Use random generator to quote the price of the item above 10,000. The thread with the highest price will win the valuable item.Implement a class that checks whether a given number is a prime numberor not using both the Thread class and Runnable interface.Explain why synchronization is necessary in the following situation:You have modeled a bank as an array of BankAccountobjects. Each BankAccount object has an associated thread, which transfers money from this bank account to another, randomly selected bank account in the same bank. The amount to transfer is the same for all transactions. The threads work in parallel.
- Write a program that creates a certain number of sellerthreads thatattempt to sell all the available tickets. There is a global variablenumTickets which tracks the number of tickets remaining to sell.We will create many threads that all will attempt to sell tickets untilthey are all gone. Each thread will exit after all the tickets havebeen sold.E.g. if we have 4 tickets and 2 sellerthreads then output should be likeSeller #1 sold one (3 left)Seller #0 sold one (2 left)Seller #1 sold one (1 left)Seller #0 sold one (0 left)Seller #1 noticed all tickets sold! (I sold 2myself)Seller #0 noticed all tickets sold! (I sold 2myself)Done Do this using semaphores and c++ linux basedWrite a program that creates a certain number of sellerthreads thatattempt to sell all the available tickets.

- Write a Java program that creates a new thread called PrintEven, that prints the Odd numbers between 1 and N. N should be sent from the main thread to the PrintEven threadThe Programming Language is; JAVA Please write comments in each part write a program about a e-shopping order menu. While doing this use OOP concepts. Implement a stocking program using threads. You have an e-store and customer side. In the frame: Number of Items (TextField): Number of items in the stock.() Create (Button): Creates items and adds them to frame. (Pen, paper, bag,etc.) Good (Button): Agents/Customer’s basket start to number of goods/items.(Customer wants to buy 3 pens) Number of Agents (TextField): How many customers at one time? (You can create an arbitrary maximum number if you explain.I.e maximum 4 customers because,...) Maximum Waiting Time (Text Field): Agents or customer’s basket will wait for some time after booking an item. The waiting time will be a random number between 0 and the number entered in this text field. Waiting times must be different for each agent. When waiting time is up, threads (baskets) will release their hold on items. So If your…Write a program that launches 26 threads. Each thread represents an English alphabet, say a, b, c, etc. Each thread should concatenate the string "+ ch " to a string variable that is initially defined as the string " " (i.e. empty string). "ch" represents the character of the current thread being executed (e.g. a, b, c,..) . Print your string variable after all threads have been executed. The targeted correct output may look like "a+b+c+d+e+…..". Run the program with and without synchronization to see its effect. Comment on the non-synchronized output.
