- Define a class MyData that holds an instance variable x, a function to increment x by 5, and a getter to return the value of x. In a MyUtil class, define an aggregate relationship where MyUtil holds a MyData reference. MyUtil should extend Thread and provide an implementation for run that contains a for loop that iterates 100000 times calling the increment function of the myData reference. Define the main method in MyUtil that creates the instance of MyData. Define a data collection for storing MyUtil objects. In three separate for loops, (1) create and add five instances of MyUtil to the data collection previously defined. (2) Call the start function on each thread. (3) Ensure each thread completes before main completes. Print out the value of x from myData. In a brief comment, describe what is happening when you execute the program several times. Also in the comment, what keyword could be used where to prevent the issue seen?Implement the producer consumer problem (also known as bounded buffer problem) in java. create two threads i.e. the producer thread and the consumer thread. Create a shared buffer object using a LinkedList or Queue. The producer adds data to the buffer and the consumer removes data from the buffer. The producer cannot add data if the buffer is full and the consumer cannot remove data from the buffer if it is empty. Make sure there are no race conditions and deadlocks.Write a MultiThreaded ServerSocket Program in C# that can handle multiple clients at the same time. a C# Server Socket use TcpListener Class and listen to PORT 9393. When the C# Server Socket gets a request from Client side, the Server passes the instance of the client request to a separate class handleClient. For each Client request, there is a new thread instant is created in C# Server for separate communication with Client.
- 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 test client TestBinarySearch.java for use in testing the implementations of min(), max(), floor(), ceiling(), select(), rank(),deleteMin(), deleteMax(), and keys() that are given in the text. Start with the standard indexing client . Add code to take additional command-line arguments, as appropriateDistinguish between the Java classes GenericServlet and Http Servlet using an example.
- Implement a class that checks whether a given number is a prime numberor not using both the Thread class and Runnable interface.Could you assist me with this code? I'm struggling to comprehend how to implement it. The code should be written in C and must involve a 5 x 5 matrix. I have the provide the question and my code. You need to use the pthread for matrix multiplication. Each threadfrom the threadpool should be responsible for computing only a partof the multiplication (partial product as shown in the above picture –all Ti(S) are called a partical product). Your main thread should splitthe matrices accordingly and create the partial data arrays that areneeded to compute each Ti. You must create a unique task with thedata and submit it to the job queue. You can compute the partialproducts concurrently as long as you have threads available in thethreadpool. You have to remove the task the from queue and submitto a thread in the threadpool. You should define the number ofthreads to be 5 and keep it dynamic so that we can test the samecode with a higher or lower number of threads as needed. When allthe partial…Write a recursive instance method named findBad that takes no parameters and returns a reference to a Link. The result of calling findBad is a reference to the first link that has a value greater than the next link's value. If no such link exists return null. For example, for {5→6→7→3→2} it would return a reference to the third link ("7").
- Implement a Queue class whose add and remove methods are synchronized. Supply one thread, called the producer, which keeps inserting strings into the queue as long as there are fewer than ten elements in it. When the queue gets too full, the thread waits. As sample strings, simply use time stamps new Date().toString(). Supply a second thread, called the consumer, that keeps removing and printing strings from the queue as long as the queue is not empty. When the queue is empty, the thread waits. Both the consumer and producer threads should run for 100 iterations.Distinguish between the Java classes GenericServlet and HttpServlet using an example.Write a multithreaded Java program that uses synchronized methods (Section 7.4.1), reentrant locks (Section 7.4.2), or semaphores (Section 7.4.3) to control access to a one- lane bridge. One thread should simulate westbound vehicles and another thread should simulate eastbound vehicles. The vehicles do not have a reverse gear, so the bridge would become deadlocked if both a westbound vehicle and an eastbound vehicle were allowed to drive onto the bridge at the same time. Therefore, mutual exclusion must be enforced on the use of the bridge. Your solution should avoid both deadlock and starvation (e.g. the bridge being monopolized by westbound vehicles while the eastbound vehicles never get to cross). Vehicles traveling in either direction should wait (sleep) for some amount of time, then attempt to cross. Once a vehicle is on the bridge, it should sleep for some amount of time to simulate how long it takes to drive across the bridge. Output a message when each vehicle drives onto the…
