How can I convert string to double?

Question

I am developing an android app. I need to convert string to double. How can I do it?

Solution 1

You just need this :

double d=Double.parseDouble(myString);

If your String value cannot be parsed to double it will throw NumberFormatException. So better you put the parseDouble statement inside try catch block.

Solution 2

here is the example

try{
   double dbl = Double.parseDouble("99.882039");
catch(NumberFormatException ex){
  // handle exception
}

Solution 3

double d = Double.parseDouble(theString);

I think the OP wanted a small-d double, but boxing is okay.

better to catch only NumberFormatException
