Strings and ints

[JS]

Hi all,
Is there anyway to read a number in from a file or similar as a String and
use it as an int variable i.e.

String s = "123";
int i = s;

The above code doesnt work because of the different types so are there any
methods anyone knows of to manage this.
Thanks in advance

What does your textbook say?

String s = "123";
int i = s;

The above code doesnt work because of the different types so are there any

Look at the documentation of the Integer class and consider asking
beginner's questions in comp.lang.java.help.
