Question
FilelO 05: Averages from a File
Write a FileI005 class with a method named calculateAverage() that takes a filename (as a String). Assume that the file only contains numerical values. Have the method calculate the average of all of the values.
Return the average as a Double. If an exception is thrown, display an informative message and return e.0.
Example
FileI005 driver
String filename
Double val
= new FileI005 ();
"numbers0.txt";
driver.calculateAverage ( filename );
// returns 58.3529411764706
filename = "numbers1.txt";
driver.calculateAverage( filename ); // returns 62.699999999999996
%3D
val =
"numbers2.txt";
driver.calculateAverage( filename ); // returns 56.828571428571436
filename
val
