     If that's what he was trying to say, he was mistaken.
On Java 1.6.0_05-b13, `new Integer("1.0")' gives me

Exception in thread "main" java.lang.NumberFormatException: For input 
string: "1.0"

.... so I don't think his "NumberFormatException couldn't catch
it" meant "No exception is thrown."  (What it *did* mean is a
mystery he's declined to elucidate.)

     If he uses the parse() method of a suitable integer-only
NumberFormat, it will stop on a '.' rather than objecting to
it.  But according to his original method, that's not what he
was doing: He was using the Integer(String) constructor, which
insists on converting the entire String, not just a prefix.
