1.7 Javadoc:
/**
* Parses the string argument as a signed integer in the radix
* specified by the second argument. The characters in the string
* must all be digits of the specified radix (as determined by
* whether [EMAIL PROTECTED] java.lang.Character#digit(char, int)} returns a
* nonnegative value), except that the first character may be an
* ASCII minus sign [EMAIL PROTECTED] '-'} (<code>'\u002D'</code>) to
* indicate a negative value or an ASCII plus sign [EMAIL PROTECTED] '+'}
* (<code>'\u002B'</code>) to indicate a positive value. The
* resulting integer value is returned.
*
* <p>An exception of type [EMAIL PROTECTED] NumberFormatException} is
* thrown if any of the following situations occurs:
* <ul>
* <li>The first argument is [EMAIL PROTECTED] null} or is a string of
* length zero.
*
* <li>The radix is either smaller than
* [EMAIL PROTECTED] java.lang.Character#MIN_RADIX} or
* larger than [EMAIL PROTECTED] java.lang.Character#MAX_RADIX}.
*
* <li>Any character of the string is not a digit of the specified
* radix, except that the first character may be a minus sign
* [EMAIL PROTECTED] '-'} (<code>'\u002D'</code>) or plus sign
* [EMAIL PROTECTED] '+'} (<code>'\u002B'</code>) provided that the
* string is longer than length 1.
*
* <li>The value represented by the string is not a value of type
* [EMAIL PROTECTED] int}.
* </ul>
*
* <p>Examples:
* <blockquote><pre>
* parseInt("0", 10) returns 0
* parseInt("473", 10) returns 473
* parseInt("+42", 10) returns 42
