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
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

Create a monitor class to manipulate a bounded buffer containing 2 methods write (adding a Double in the buffer) and read (taking a Double from the buffer). Create a producer thread and consumer thread using the Thread class.
Implement the server-side requirements and then provide code snippets for each function with clearexplanation/comments of key statements used.i. Create a thread using extending thread class or implementing runnable interface and implementa run method with explanations of the method usedii. The server will read the employee ID, employee name, number of doses, and vaccination status(unvaccinated, partially vaccinated, and fully vaccinated). The server will then connect to thedatabase and add the inputs as a new recordiii. The server will then calculate the number of unvaccinated, partially vaccinated, and fullyvaccinated employees. The server will then send the results to the client for display.
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. B) Write a main program to calculate the factorial of a given number n (). 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
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…
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
