This is an example that shows how to use the Join () method.Problem:Computes the value of an expression 1*2/(1+2) using Java multithreading.Solution:Use one thread to do the addition, the other to do the multiplication, and the main thread to do the division. Because there is no need for communication between threads, we only need to consider the order in which threads are executed.In the main thread, we let the addition and multiplication threads joi
