public static int parseInt (String s) throws NumberFormatException

Parses the string argument as a signed decimal integer. The characters in the string must all be decimal digits, except that the first character may be an ASCII minus sign '-' ( '\u002D') to indicate a negative value or an ASCII plus sign '+' ( '\u002B') to indicate a positive value. The resulting integer value is returned, exactly as if the argument and the radix 10 were given as arguments to the parseInt(java.lang.String, int) method.

s    a String containing the int representation to be parsed

Returns:  the integer value represented by the argument in decimal.

NumberFormatException    if the string does not contain a parsable integer.
