- URGENT URGENT URGENT !!! You should implement four threads in Java. The execution should be in this order: Thread 2, Thread 3 and finally Thread 1. Thread 0 Used to call other threads You have to use join() method Thread 1 Should be implemented using extends Thread Thread class (extends Thread) You have to use for loop Priority Max Thread 2 Should be implemented using Runnable interface You have to use for loop You have to use sleep() method (one second interval inside the loop) Priority Normal Thread 3 Should be implemented using extends Thread Thread class (extends Thread) You have to use for loop You have to use sleep() method (4 seconds interval before the previous thread) Thread Priority 7 The output should be as following: 1 Thread 2 (University number) 2 Thread 2 (University number) 3 Thread 2 (University number) 4 Thread 2 (University number) 1 Thread 3 (University number, Thread Priority) 2 Thread 3 (University number, Thread Priority) 3 Thread 3…Hello, could you assist me with this code? I'm encountering difficulties and I'm unsure how to proceed. The code needs to be written in C. I've included my current code below for reference.question:You need to use the pthread for matrix multiplication. Each thread from the threadpool should be responsible for computing only a part of the multiplication (partial product as shown in the above picture –all Ti(S) are called a partical product). Your main thread should split the matrices accordingly and create the partial data arrays that are needed to compute each Ti. You must create a unique task with thedata and submit it to the job queue. You can compute the partial products concurrently as long as you have threads available in the threadpool. You have to remove the task the from queue and submitto a thread in the threadpool. You should define the number of threads to be 5 and keep it dynamic so that we can test the same code with a higher or lower number of threads as needed. When…Select all that are true regarding variables and threading. A) atomic variables ensure operations on them are all or nothing B) volatile variables disable local caching of it C) atomic variables completely eliminate race conditions D) access to volatile variables are less efficient than synchronized variables

Use the way of extending the class thread. Write the main method which creates and starts three threads Printer which will print different arrays of integers. After that it prints "Main won’t wait. Main exits". Modify the above thread program so that you implement the interface Runnable.

You have to design a multithreadedsystem in java for your CSE110 course. So, you are assigned a job with followingdescriptions. You have to design a class NumberComputator which has a functionprintComposite(int n) that can take a parameter N and print the composite numberfrom 1 to nth term. Composite numbers are the number that are not prime number.Again, create two thread class (ThreadOne, ThreadTwo) by extending the Threadclass so that all of the thread should call the method “printComposite(int n)” of theNumberComputator class. Again, write a main java class named“MultiProgrammingDemo” with a main method that instantiate two objects of twothreads(ThreadOne, ThreadTwo).Your task is to process and run two threads simultaneously in the main method byconsidering the fact that when one thread printing with the printComposite(n)function the other threads must be wait for the completion of the work the initial thread.Design a JAVA…Could you kindly utilize solely my code as I contributed to its development?
