The data * should be loaded one line of text at a time using the Scanner's nextLine * method. The first line of text should be discarded as it is a header. Each * line of text, stored in a String, should be split using the .split(",") * method. This will create an array of Strings. The relevant Strings are index * 1, which indicates the date for the data on this line, index 2, which will * indicate if the day contains multiple days of precipitation (or will be blank * if it is just a single day of data), index 3, which indicates a multiple day * precipitation total (or will be blank if it is a single day of * precipitation), index 4, which indicates the single day precipitation total * (or will be blank if the day contains multiple days of precipitation), index * 7 which indicates the day's high temperature (and may be blank if this was * not recorded), and index 8 which indicates the day's low temperature (and may * be blank if this was not recorded). All other indexes may be ignored. All * non-blank indexes in the array will contain a string surrounded by quotes - * the substring command is the easiest way to get rid of them. Temperatures are * always integers but precipitation and snowfall totals may contain decimal * points.
