Please answer in JAVA PROGRAMMING Q)write code using your name and parents as objects in polymorphism? NOTE:MY NAME IS MEHBOOB ALI

Consider the following data that are shared between two threads and are initialised before the threads are executed, as follows: boolean flag = true; int x = 50; Thread 1 is defined as follows: void run_thread1() { while (flag) { } print x; } Thread 2 is defined as follows: void run_thread2() { x = 60; flag = false; } Let us assume that, as there are no data dependencies between the variables flag and x, it is possible that a processor may reorder the instructions for Thread 2. Which of the following statements regarding the possible output of Thread 1 is TRUE? Thread 1 could enter an infinite loop The output could only be 50 The output could either be 50 or 60 None of the mentioned The output could only be 60

JAVA PROGRAMMING You are required to create a main class to apply ExecuterService with SingleThreadExecuter. The variable i is integer number and MUST be input from the keyboard. Output should be like this: Please input i: 3 pool-1-thread-1: 1 pool-3-thread-1: 1 pool-3-thread-1: 2 pool-3-thread-1: 3 pool-2-thread-1: 1 pool-2-thread-1: 2 pool-2-thread-1: 3 pool-1-thread-1: 2 pool-1-thread-1: 3 Total = 9Below is the part of code.class Counter public class Counter { private int counter; public void increment(){ counter++; } public void decrement(){ counter--; } synchronized public void myIncrement(){ counter++; } synchronized public void myDecrement(){ counter--; } }

Write a Java program using Thread with single Server and Multiple Clients. NOTE: Client must be running until Bye message is sent. Server should never stop. I need answer question pls

Hello Can you please help me with this code because I am struggling how do to this, can you please help me this code has to be in C. Write a multithreaded program that calculates various statistical values for a list of numbers. This program will be passed a series of numbers on the command line and will then create three separate worker threads. One thread will determine the average of the numbers, the second will determine the maximum value, and the third will determine the minimum value. For example, suppose your program is passed the integers 90 81 78 95 79 72 85 The program will report The average value is 82 The minimum value is 72 The maximum value is 95 The variables representing the average, minimum, and maximum values will be stored globally. The worker threads will set these values, and the parent thread will output the values once the workers have exited. (We could obviously expand this program by creating additional threads that determine other statistical values, such as...

Please answer the follwoing regarding the java code: When looking at the code below, assume that the MyThread and MyRunnable classes are correctly implemented in other files. How many threads are there in the program shown below? (Be careful to consider ALL the threads!)

Fill in the blanks:5. The ( 6 ) is used to implement mutual exclusion where it can be decremented by aprocess and incremented by another, but the value must either be 0 or 1.6. If deadlock prevention approach is used to deal with deadlocks in a system, the ( 7 )condition can be prevented using the direct method.7. Two threads may share the memory space, but they cannot share the same ( 8 )8. Consider round-robin (RR) scheduling algorithm is implemented with 2 seconds timeslice and it is now selecting a new process; if we have 3 blocked processes (A, B, and C),and A has been waiting the longest, then A would need to wait a period of ( 9 ) secondsto be selected.9. In real-time systems, if a task appears at random times, then it is considered ( 10 ).

Please help with the following In Java:

: Suppose we have the following code:public class Foo {public Foo() { ... }public void first() { ... }public void second() { ... }public void third() { ... }}The same instance of Foo will be passed to three different threads. ThreadA will call first,threads will call second, and thread( will call third. Design a mechanism to ensure thatfirst is called before second and second is called before third.

Consider the below Java code. import public class Semaphore Demo java.util.concurrent.Semaphore; Semaphore binarySema= new Semaphore (1); public static void main (String args[]) { final SemaphoreDemo sema DemoObj= new Semaphore Demo (); Thread td1= new Thread() ( public void run () { } }} } }; Thread td2= new Thread () { @Override public void run () { sema DemoObj.testMutualExclusion (); } sema DemoObj.testMutualExclusion (); tdl.start(); td2.start (); private void testMutualExclusion () { try { binarySema.acquire(); System.out.println (Thread.currentThread().getName()+ "inside the region of mutual exclusive."); Thread.sleep (1000); } catch (InterruptedException e) { ie.printStackTrace(); } finally ( System.out.println (Thread.currentThread().getName() + "outside the region of mutual exclusive."); What would be the output of the program?

Multi-tasking can not be achieved with a single processor machine. True False 2. Async/Await is best for network bound operations while multi-threading and parallel programming is best for CPU-bound operations. True False 3. The following is a characteristic of an async method:The name of an async method, by convention, ends with an "Async" suffix. True False 4. Using asynchronous code for network bound operations can speed up the time needed to contact the server and get the data back. True False 5. Asynchronous programming has been there for a long time but has tremendously been improved by the simplified approach of async programming in C# 5 through the introduction of: The Task class True False

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...
