Having trouble converting from string to in

[daph]

Hi everyone,

I'm new to JSP and I've been trying to do some basic stuff to get used to it. Now, I've been trying to convert a string to a int, but no matter how I try it, I get errors. What package do I need to import for this? What function should I use? I tried Integer.parseInt but that didn't work either.

I was also wondering how I can import more than one package with this line
<%@ page contentType=&quot;text/html&quot; import=&quot;java.util.*&quot; %>
Do I have to add more than one line or can I add more into this one?

Thanks for all your help...I really appreciate it!

Integer.parseInt is definitely what you want. Make sure that you catch a NumberFormatException in case the input is invalid.

String s = "2";
int i;
try {
  i = Integer.parseInt(s);
}
catch(NumberFormatException nfe) {
  // invalid number
}

To import more than one package just separate with commas.

<%@page language=&quot;java&quot; import=&quot;java.util.*,java.text.*&quot; %>
