-----------------------------------

That can only input string I though, or if Im mistaken I have to change the tutorial. You still end up use Double.parseDouble.

It's not tested, but...

import java.lang.*;
import java.io.*;
import java.util.*;

class Test
{
   public static void main(String[] args)
   {
      BufferedReader keyboard = new BufferedRead(
         new InputStreamReader(System.in));

      // read in a line
      String userInput = keyboard.readLine();
      
      // store the double input
      doube parsedUserInput = Double.parseDouble(userInput);

      // do something with the double
   }
}
