- 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…1)Write a complete multi-threaded Java program to find product of 2 matrices of any size. Write a Driver class containing main method to read dimensions and the elements of 2 matrices from keyboard. Check whether the two matrices are compatible for multiplication or not. If not, throw an user defined exception called IncompatibleMatrixException. Write a MatThread class using Runnable interface. Each thread will find one row of a resultant matrix. Pass only the necessary data to the thread class constructor. Display the rows of the resultant matrix from respective threads along with the thread names like Row 0, Row 1 etc.The following question is related to Threading Task-1: Write a c program that creates 5 threads and prints which thread is running and after the thread is closed, a new thread starts its execution. Each thread should run sequentially one by one. OUTPUT: thread-1 running thread-1 closed thread-2 running thread-2 closed
- 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.(a) Write a simple C program using pthreads in which the main thread creates a single worker thread and passes an integer value to the thread function. The thread function outputs the integer data on the screen. (b) Write a simple C program using Pthread to create one worker thread that print “Hello”. After which the main thread joins the worker thread.10 Write a C program that creates five threads (in addition to the initial thread) and makes each execute a function task(void * i) for i integer ranging from 1 to 5. in this function, make an empty loop of 10000 steps, then display of the i number and the thread id on the screen. The initial thread will also perform the display. Check on this example that: — The use of the exit() function in one of the threads of the process leads to the termination of all the threads. — The termination of the initial thread leads to the release of all the resources, therefore the termination of all the threads of the process. How to avoid this premature termination?
- 1. Implement mutual exclusion with multithreading in Java Build a Java program which simulates a communication between a server and clients. You must use a thread to represent each party (as server or client). (Hint: study about the Semaphore class to perform mutual exclusion between threads) Create three threads. One thread will act as a server, which always ready to receive a message from a client (ping) and then replies the message to the same client (pong). The other two threads will become the clients, where each client will send a message to the server (ping) and waits for the reply (pong). Define 2 different classes to represent the server and the client. To perform the communication, each thread will refer to a same variable/data structure for sending and receiving the message. Use mutual exclusion approach to ensure each client can send and receive the reply without interruption from any other elient(s). For this simulation, your objective is to ensure that each client must…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).

Use code below. #include <stdio.h>#include <stdlib.h>#include <unistd.h>#include <pthread.h>#include "common_threads.h" typedef __ns_mutex_t {} ns_mutex_t; void ns_mutex_init(ns_mutex_t *m) {} void ns_mutex_acquire(ns_mutex_t *m) {} void ns_mutex_release(ns_mutex_t *m) {} void *worker(void *arg) {return NULL;} int main(int argc, char *argv[]) {printf("parent: begin\n");printf("parent: end\n");return 0;}
- Write java code to create a thread by (extending), theprogram create 3 thread that displaying “fatmah” and thenumber of thread that is running.Rewrite the above program by implementing the RunnableInterfaceQUESTION 8: Practical (a) Cold Code Provide Java source code for the following problem. You can assume that all relevant packages have been imported. Provide a class called PrintMessage that is a task that can be run on a Thread. The constructor of PrintMessage sets the message to be displayed and repeat value, a number that represents the number of times the message must be displayed. When PrintMessage is started it prints the message to System.out then waits 200ms, this process is repeated based on the repeat value. Provide a Main class that instantiates a PrintMessage with appropriate values, loads the instance onto a Thread and starts it.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
