a. Using Java multithreading library, write a Java program that calculates the sum of the numbers from 1 to 100,000,000. Split the numbers between four threads equally where each thread calculates the sum of one fourth of the numbers. For example, the 1st thread will calculate the sum of the numbers from 1 to 25,000,000 whereas the 2nd thread will calculate the sum of the numbers from 25,000,001 to 50,000,000 and so forth. The main thread will have to print out the sum after gathering the results. Note that you have the choice to create threads by either implementing Runnable interface or extending Thread class. b. Now, write a sequential version of the program described above using a single main thread (i.e., without multithreading). Make sure to record and print out the time spent during the execution of both sequential and multithreaded versions (hint: you may consider using System.currentTimeMillis() to record execution time),

Exercise 1: Write a thread class TabPrinter that prints the elements of an array of integers (in one line) every 2 seconds 5 times. 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. Make the main thread waiting till all other threads finish execution. ____________________________________________________________________________________________ Exercise 2: Write a thread class TextThread that prints a text every 1 second 10 times. Read the following main class. Try to guess what will be its output. class Test { public static void main(String s[]) throws Exception { TextThread x = new TextThread ("I am thread x"); TextThread y= new TextThread ("I am thread y"); System.out.println("I am Main thread"); } } Write it and execute it. Is the…

Could you kindly utilize solely my code as I contributed to its development? I emphasize, please utilize only my code.I attached my code below label my code.   The question that I need help with: 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…

Steps to be followed: Create a class called MyThread that extends the Thread class. Declare an instance variable int limitToStop in the MyThread class. Create a parameterized constructor in the MyThread class that takes an int as a parameter to initialize a limitToStop instance variable. Override the run() method in the MyThread class. In the run() method, put a for-loop that goes from 0 to limitToStop. The block associated with the for-loop should print out only the odd numbers. Call Thread.sleep(1000) after every number you print out in the for-loop you created in the previous step. The Thread.sleep(1000) method throws an InterruptedException , which is a checked exception. Therefore, we need to enclose the Thread.sleep(1000) call in a try block. Also, add a catch block associated with the try that catches the InterruptedException and prints out the exception information using the printStackTrace() method. Create a MyThread variable using the new keyword in the main()…

in java fx Write a program that launches 1,000 threads. Each thread adds 1 to a variable sum that initially is 0. You need to pass sum by reference to each thread. In order to pass it by reference, define an Integer wrapper object to hold sum. Run the program with and without synchronization to see its effect.
