/*
 * Write an application that reads daily temperatures for 12 months and allows
 * the user to get statistics. Support at least three options: monthly average
 * of a given month, yearly average, and lowest and highest temperatures of a
 * given month. Use a text file to store temperatures. A line in the text file
 * contains daily temperatures for one month. The first line in the text file
 * contains temperatures for January; the second line, those for February; and
 * so forth. Using StringTokenizer to parse a line into temperatures of type
 * float. For a data structure, consider using either an array of Month or a
 * two-dimensional array of float. Month is a class you define yourself.
