Double d = Double.valueOf(stringRepresentationOfDouble);
as David suggested to read in the value correctly, then
double dbl = d.doubleValue();
to get the double value from that, or of course just:
double dbl = Double.valueOf(stringRepresentationOfDouble).doubleValue();
Alternatively, some (most?) databases would accept the value in String format so just concatenate the Double into your SQL query/update once you've verified it's format.

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

or
Double d = new Double(stringRepresentationOfDouble);(remeber to catch NumberFormatException)
dvae.
P.S. Please refer to documentation (trying to be polite but RTFM :).
