Dear All,

If you are interested in not just codding but not repeating your code in any where, I must recoomend ou to read Rob Martin. Uncle Bob, is the man who taught me what OOP really does. Mainly Solid, and not writing the same things n times instead calling the same method or whatever n times, you must read Clean Code. Then, Clean Coder. Tha language is pretty simple for everyone to understand!
