Review of Basics: Control Statements, Repetition, ArrayLists, Methods and Text File IO Write a program to read student data from a text file which is attached to the drop box as This file is in the format: Student ID (int) Full name (last, first) (String) Test score (double) We need to process this data: - Read data from the file. *Calculate the average score for the group * Determine whether a particular score is greater than, equal to or less than the average Derive a letter grade for each numeric score Calculate the standard deviation of the group of scores Display output as shown in the sample below. - * * Because of this, we'll need to maintain lists of data in memory. We could use arrays of IDs, names, scores, etc.; however, the trend is to use more flexible structures like ArrayLists, Vectors or Linkedlists because, unlike fixed size arrays, they can expand to hold more data as needed. The rules for deriving a letter grade are: Numeric grade >= 90, " Numeric grade >- 80 and - 70 and - 60 and Average
