Write a method that recursively converts a string of numbers into an integer. For instance, convert("1234") would return the integer 1234.

In the Java API (downloadable here if you don't have it: http://java.sun.com/j2se/1.4.1/download.html#docs) browse to java.lang.Integer and learn how the parseInt(String s) method works. This should be helpful in creating your method.

Also make sure that you remember to provide code to handle the NumberFormatException(s) that java.lang.Integer.parseInt(String s) will throw if the String argument is not correctly formatted.

Hope this helps you get started on your project.

This seems to me to be a homework. Is it really so difficult to treat 1 character at a time and call recursively for the rest????
