How can I convert a String such as \"12.34\" to a double in Java?
Citing the quote from Robertiano above again - because this is by far the most versatile and localization adaptive version. It deserves a full post!
Another option:
DecimalFormat df = new DecimalFormat();
DecimalFormatSymbols sfs = new DecimalFormatSymbols();
sfs.setDecimalSeparator(',');
df.setDecimalFormatSymbols(sfs);
double d = df.parse(number).doubleValue();
