You can do it in the following way :
String s = "10.1";
Double d = Double.parseDouble(s);
The parseDouble method will achieve the desired effect, and so will the Double.valueOf() method.

If you have problems in parsing string to decimal values, you need to replace "," in the number to "."
String number = "123,321";
double value = Double.parseDouble( number.replace(",",".") );
