String to Integer problem Posted: Jul 15, 2006 3:25 AM

Hi,

I'm new to JSP and I have problems converting String with decimal numbers to Integer.

I have a string with 8 decimals, it gets the vallue of a column in database. I would like to make a sum of all the rows. Example:

while (rs.next()) {
String sumi = rs.getString("amountduration");
int sum = Integer.parseInt(sumi);
// Code for making the sum
// ..
}

It appears that "Integer.parseInt" works only if the string doesn't have any decimals.

Thanks
Zark

Integers are whole numbers. They have no fractional part.

You should be using doubles instead.

double sum = Double.parseDouble(sumi);
