Getting index from a select object?

[JS]

I have the following selectbox in my jsp page:

<select name="myNumber" >
<option value="1">One
<option value="2">Two
<option value="3">Three
</select>

<%
String myNumber = request.getPara meter("myNumber ");
int n = Integer.parseIn t(myNumber);

%>

With this javacode I am able to store the index of the option choosen from
the select object, in n.

But I think its confusing that converting the name of an option into a int
gives its corresponding value.

Normally that would throw a NumberFormatExc eption:

String z = "Peter";
int k = Integer.parseIn t(z);

throws exception.

How can it be legal to convert String "myNumber" into an int?

Java is to JavaScript as Car is to Carpet[1]. Posts about Java Server Pages
should be addressed to a Java newsgroup.

could remember who.
