Next Double from a String

I have used a Scanner Object before to read doubles from an input, but how do I get the Next double from a String?

Used this in the past:

Scanner input =new Scanner(System.in);

double num = input.nextDouble();

I am looking for something like this:

String example ="100.00";

double num = example.nextDouble();

Any suggestions?
