When to print a number using three threads?
Unless the assigned thread number is not equal to the remainder of the number division by 3, thread is made to wait. Only when the assigned thread number is equal to the remainder of the number division thread prints the number and notifies other waiting threads so that one of them can enter the synchronized block.
How is the number of threads assigned in Java?
In the program each thread is assigned a number (0, 1 and 2 respectively). Before thread prints a number, each number is divided by 3 and the thread which has an assigned number equal to the remainder of this division is eligible to print the number.
Which is an example of multithreading in Java?
Multiple threads are usually used to compute things in parallel. In this example nothing is computed in parallel: while one thread is running, the other is waiting. With no practical value, it’s not a great demonstration of multithreading.
How to print even and odd threads in Java?
In Odd thread as odd Sema is available (init to 1) this will print 1 and then release even Sema allowing Even thread to run. Even thread runs prints 2 and release odd Sema allowing Odd thread to run.
Can you print with 10 threads in Java?
Hold a List and every thread will insert into the list, in the end you can sort and print.. If you want them to do it on your order it won’t be very effective because you won’t need 10 threads to do it.. This way it will be faster and will use 10 threads to do some work, but when everyone finish you still need to do some work
How to print numbers in sequence using synchronization?
Here we will see how to print numbers in a correct sequence using different threads. Here we will create n number of threads, then synchronize them. The idea is, the first thread will print 1, then second thread will print 2 and so on. When one thread is trying to print, it will lock the resource, so no thread can use that portion.
