Tip: I wanted to give you a tip that will help you streamline your studies / work with programming. Your situation is: you have Array of Cartas and you need to shuffle these Cartas ... You do not need to lock in Cartas but in the resources you are using ( Array ).

If every Carta is within a Array , then you need to randomize a Array what you have inside Array does not matter (in your case they are Cartas ) or you would have gained much more If you had searched for "How to randomize a Array " and would have already found the solution, you would not have to wait for an answer here. Well, it's not a negative criticism, but constructive I hope it helps.
