Hi,
double doubleValue = (new Double(doubleString)).doubleValue();
Will convert a Double object to the equivalent double value. See example
code that follows if confused.
You may like to concider using a float, if values are going to similar to
0.5. It will half your memory requirements!
Hope that helps,
Dan.
import java.lang.*;
public class DoubleStringTest{
public static void main(String[] args){
String doubleString = "0.5";
double doubleValue = (new Double(doubleString)).doubleValue();
System.out.println(doubleValue);
}
}

Subject: Re: another basic question
But this is my problem, but I don't want a DOUBLE OBJECT,
I want a DOUBLE VALUE / TYPE. I have tried the below method but then I
have the problem of converting the Double d object to the value which the
database will take without throwing an exception because it wants a double
whilst I am giving it a Double And it is this that is causing me the
grieve.
I tried the Double.parseDouble, but I just get : not found in
java.lang.Double

Double d = Double.valueOf(stringRepresentationOfDouble);
or
Double d = new Double(stringRepresentationOfDouble);

dvae.
P.S. Please refer to documentation (trying to be polite but RTFM :).
