How do I convert a value of type string that needs to be stored in a variable that is of the type int? Here are some conversion codes which are most appropriate to use in this conversion?
A.a = Integer.valueOf("10")
B.a = int.Parse("10")
C.a = Convert.Numeric("Macedo")
D.a = Convert.ToNumeric("10")
E.a = int.Convert.valueOf("Macedo")

Java provides the following method:
int one = Integer.parseInt("1"); // Retorna um tipo primitivo (int)
This method takes a string and converts to an integer, just as you need.
Integer one = oneInteger.valueOf("10"); // Retorna um Objecto Integer
int.parse("10"); // Não existe porque um tipo primitivo não pode ter métodos associados
As for the other examples, these methods simply do not exist.

Ezar, welcome to [pt.so]! This is not Java. Please edit your question and add more information about the language, the version you are using and what you are trying to do, after all each conversion mode can have strengths and weaknesses. Hug!
