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()…Write program for the following Create a child thread class for sorting an array of 10000 size string values Create a child class for calculating factorial of 50 Create a child thread class for calculating base b to the power p Create a single object of each thread in the main thread, and stop the execution of main thread until the termination of all child threads using join method
- Part 1: Thread creation (30%)a. Using Java multithreading library, write a Java program that calculates the sum of the numbersfrom 1 to 100,000,000. Split the numbers between four threads equally where each threadcalculates the sum of one fourth of the numbers. For example, the 1st thread will calculate the sumof the numbers from 1 to 25,000,000 whereas the 2nd thread will calculate the sum of the numbersfrom 25,000,001 to 50,000,000 and so forth. The main thread will have to print out the sum aftergathering the results. Note that you have the choice to create threads by either implementingRunnable 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 ofboth sequential and multithreaded versions (hint: you may consider usingSystem.currentTimeMillis() to record execution time).Part 2: Synchronization (40%)Assume…Part 3: Interrupt handlingIn Java multithreading environment, one thread can send an interrupt to another by calling theinterrupt() method on the Thread object for the target thread (i.e., the thread to beinterrupted). To handle interrupts in a target thread, Java allows two approaches. One is performedby writing an exception handler for InterruptedException (only applicable if the targetthread is invoking methods which throw that exception such as sleep). The other approach isperformed by periodically checking the interrupt status flag Thread.interrupted andperforming the handling routine when that flag is set to true.Write a Java program that illustrates the use of the two approaches described above. Your programshould start by creating two threads, each thread should use different interrupt handling approach.Then, the program needs to send interrupts to each one of the created threads such that a threadneeds to return (i.e., stop execution) after receiving an interrupt from the main…THREAD -"C LANGUAGE" ONLY Write a program that uses 5 threads. Initialize a shared variable with a value of 0. Each thread must add its Thread ID (tid) to the shared variable. Once a thread has done the addition, print the ID of the thread. It is important to make use of mutexes so that only one thread is incrementing the shared variable at a time. Output the value of the shared variable once all threads have finished incrementing it.
- **CENAGE PYTHON** Question: Redo the producer/consumer program so that it allows multiple consumers. Each consumer must be able to consume the same data before the producer produces more data. The program should Print the message Consumer # starting up, where # is the number of the consumer starting from 0. The producer will set the data as many times as there are accesses, giving each consumer thread a chance to access the data each time. The producer should set the data to 1 initially, and then increment it for each additional access. After each consumer has consumed the data for each access, print the message Consumer # is done consuming, where # is the number of the consumer starting from 0. A sample program execution is shown below. Note that the order of the consumer start ups and accesses may vary with each program execution. Enter the number of consumers: 2 Enter the number of accesses: 3 Starting the threads Producer starting up Consumer 0 starting up Consumer 1 starting up…Write complete Java code to define a thread for printing all the Odd Nos from 1 to 5000 which are divisible by 9.
