Convert 5.1 How do I convert a string string to an integer int?

A. There are two methods:

1). int i = Integer.parseint ([String]); Or
i = Integer.parseint ([string],[int radix]);

2). int i = integer.valueof (my_str). Intvalue ();

Note: The string turns into a Double, Float, Long with a similar method.
