Write a static method called weave that that takes two integers as parameters and that returns the result of weaving their digits together to form a single integer. Two numbers x and y are weaved together as follows. The last pair of digits in the result should be the last digit of x followed by the last digit of y. The second-to-the-last pair of digits in the result should be the second-to-the-last digit of x followed by the second-to-the-last digit of y. And so on.

I really do not understand the "property" and the "setter". The "property" makes the attribute read-only, but the "setter" makes the attribute mutable. So if we want to use "property", why we need to introduce the "setter".
