Convert a string value into an int

Question

How to convert string value into int? I am getting number format exception.

String s = "20.00";
int i = (Integer.parseInt(s));
System.out.println(i);

Result should be like i=20.

Answer 1

What about:

int i = (int) Double.parseDouble(s);

Of course, "20.00" is not in a valid integer format.
