Solution: Create Random Number and Print a Square and a Cube via Threads

Learn how to write a program in which the first thread produces random numbers, the second thread prints the square of the number, and the third thread prints the cube of the random number.

We'll cover the following...

The solution to the problem of writing a program in which the first thread produces random numbers, the second thread prints the square of the number, and the third thread prints the cube of the random number is below.
