String to integer

[Jabber]

Hi,

I'm searching for a way to convert a string to an integer.
In a Jsp I call something from a database. Then I make an
diagram as follows :

<IMG SRC="/images/red.gif" width="10"
height="<%= rs.getString("Waarde_num") %>">

But Waarde_num is way to big. So I wanted to make it smaller,
like <%= rs.getString("Waarde_num") %> / 100. The way this isn't gonna work
because of <%= rs.getString("Waarde_num") %> is a string.

Please help me !!
Thanx in regards,
Jaap

If the database field is actually an integer then read it from the database
as an integer:

rs.getInt("Waarde_num")

If its stored as a String you can use the Integer.parseInt() to parse a signed
decimal integer from a String.

If its already an Int in your DB then you can do the following:
<%= rs.getInt("Waarde_num") / 100 ) %>

or if it is infact not already an Int then you can do this:
<%= Integer.parseInt(rs.getString("Waarde_num")) / 100 ) %>
