Implement three classes: A, B, and C. The class A must store an integer. The class B should create a thread that starts counting prime number from 1 to 100 and stores each value in the class A. The class C should create a thread that keeps reading the value in the class A and printing it. Write a java program that creates an Instance of the class A and sets up a B and a C object to operate on it Also, ensure that each number is printed exactly once, by adding suitable synchronization.
