Modify Assignment #10 so that it can take positive, zero, and negative floating point numbers and calculate the mean and standard deviation. Input ends when the user enters a string that can not be interpreted as a floating point number. Use exception handling to detect improper inputs.

This was my assignment 10 code, this is my example to use

try}

String filename = ....;

Scanner in = new Scanner(new File(filename));

String input =in.next();

int value = Integer.parseInt(input);

.......

{

catch (IOException exception){

exception.printStackTrace();

}

catch (NumberFormatException exception){

System.out.println(exception.getMessage());

}
