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 handling (30%)In 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…

**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. Thread must sleep for 5 seconds. Implement the threading using the Runnable java provided Interface. Finally, create three different threads with names ThreadOne, ThreadTwo and ThreadThree in main(). Execute the code in the file where threading is implemented. Apply the Java multithreading exception handling mechanism properly

Each slave thread will fork/spawn two new slave-threads where each new slave-threadsums half of the array segment received by its parent. Each slave thread will return the subtotal to its parent thread and the parent thread aggregates and returns the total to its parent thread.

Write a multi thread C++ code that adds an array of 1000 numbers. This program will be passed a number on the command line and then create threads accordingly. The array should be evenly distributed according to the number of threads. Each thread calculates its sum and then the main thread displays the final sum.
