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 Retun the average as a Double. If an exception is thrown, display an informative message and return e.e. Example: FileI005 driver = new FileI005 (); String filename- "numberse.txt"; Double val = driver.calculateAverage( filename ); // returns 58.3529411764706 filename- "numbers1.txt"; val - driver.calculateAverage( filename ); // returns 62.699999999999996 filename - "numbers2.txt"; val - driver.calculateAverage( filename ); // returns 56.828571428571436
