DQ1 – Multithreading 
I am not sure that my post will be out of scope or not, but I am also sure that following this direction before the end of this week I will have a good knowledge of multithreading in general and in Java. 
For this DQ I have tried to convert the output value as well as designing three additional class to implement a multithreading non-sync approach that should archive almost the same aims. 
Instead of using the code and translating the result of the output, also in this case I have tried to reach the same scope implementing a simple solution that allow us to push Strings taken from an array to an ArrayList using two threads and using both methods such as runnable and manually creating/extending the Thread class.
This is my first experience using multithreading in programming, therefore I am not pretending that you will understand what I have done, but as I think that this topic needs to be understood from the very basic and as far as I have understood from the DQ1 requirements, our purpose was to translate an array or its output starting from a code that has been written by another person, I should say that it will not longer be useful for me now, since I have not this kind of knowledge yet, even if I tried and made a simple conversion using a Conversion class.
In the attachment you will find both the original DQ with the conversion class as well as the application that I have designed. 
In my example I have not used the synchronization as per specific of the first example, I have used it in the DQ2 with another kind of example.
Now its time to came back to my DQ, and after this boring introduction, I will explain my personal point of view about the difference between the first example and the second and I will show you the three classes that I have used:
The main difference between the first and the second example is the use of the thread synchronization that guaranteed the programmer that a second thread cannot influence the behavior…
