In execution of a program a new thread (A) is created and begins in the New state. As it requires an input from the user, the schedular is called and changes it into the runnab state. Finally it gets a time slice from the processor but suddenly a new urgent thread (B) appears which needs to be handled by the CPU. Thus, the thread (A) is blocked and moved back to the run queue.

At the moment, work is being done by a thread with the priority 30. If (a) it used up all of its time quantum, what would be its re-assigned priority? If b is correct, then I/O has been blocked.
When a thread is active on a Java virtual machine (JVM), the JVM only permits that thread to execute a single method at a time. Do you have any proof to back up your suspicions or do they remain just that?
Create two Thread subclasses, one with a run() that starts up, captures the reference of the second Thread object and then calls wait(). The other class run() should call notifyAll() for the first thread after some number ofn seconds have passed, so the first thread can print a message
Solve the following problem in C programming language: Four threads will run in parallel. The threads have a shared variable x. The initial value of x is equal to 0. The critical section of Thread1 and Thread3 will increment the value of x by 1, while the critical section ofThread2 and Thread4 will decrement the value of x by 2. The program will return the final value of x which will be equal to 2.
A thread with the priority of 30 is presently running. What would its new priority be if it: (a) used up all of its time quantum? (b) I/O was obstructed?
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 the main thread. Make sureto…
Multi-threading A) Write a Thread class (called worker) that takes two numbers (A and B, A < B) and calculates the products of all numbers between A and B. the result is stored in a local variable than can be accessed through a get method. ). The main thread reads n from the user, then creates two instances of Worker. Each one is requested to calculate the half of numbers between 1 and n. Once they finish, the main thread will gather their results and print the final result (result1 x result2). Example when n=10
Design a food ordering system where your python program will run two threads, Place Order: This thread will be placing an order and inserting that into a queue. This thread places new order every 0.5 second. (hint: use time.sleep(0.5) function) Serve Order: This thread will serve the order. All you need to do is pop the order out of the queue and print it. This thread serves an order every 2 seconds. Also start this thread 1 second after place order thread is started. Pass following list as an argument to place order thread, orders = ['pizza','samosa','pasta','biryani','burger'] This problem is a producer,consumer problem where place_order thread is producing orders whereas serve_order thread is consuming the food orders. Use Queue class.
Make a C / C++, Java, or Python program with two processes (or threads, whichever is easier for you to code), a producer and a consumer. If you want to use another language, clear it with me first. The producer process/thread consists of a loop that writes the loop count (a value from 0 to 4) into a variable that it shares with the consumer process/thread (this variable is to be initialized to 100). On each pass through the loop, before the producer writes into the shared variable, it does a random wait of from one to three seconds (compute a new random wait value on each pass through the loop). The loop is to be executed five times. The consumer process consists of a loop that reads the variable it shares with the producer five times and computes the sum of the values it has read. On each pass through the loop before it reads the shared variable, it does a random wait of from one to three seconds (compute a new random value on each pass through the loop). When the loop finishes, the…
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
Does it make sense for a virtual machine's threads to be compelled to use the same method space?
design a java program that implements thread priority based on setPriority() method using different level of priority for two threads .Both these threads donot run on preemptive platform in the same way.Thus,prioritize the threads by running each thread for few seconds.After this main thread stops this thread.Moreover, the program should display the no of times each thread made it through the loop is displayed
