copied!<p>I just threw this together quickly, but what about something like:</p> <pre><code>static final String[] DAYS = { "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday", "Sunday" }; public class ActivityEvent { public int day; public String name; public String typeOfExercise; public String time; } public List loadActivities(String filename) throws IOException { List activities = new ArrayList(); FileInputStream fis = new FileInputStream(filename); InputStreamReader isr = new InputStreamReader(fis); BufferedReader br = new BufferedReader(isr); int lastDay = -1; String line; while ((line = br.readLine()) != null) { line = line.trim(); int day; for (day = DAYS.length - 1; day >= 0; day--) { if (line.equals(DAYS[day])) { break; } } String name; if (day < 0) { day = lastDay; if (lastDay < 0) { throw new IOException(filename + " must start with day of week"); } name = line; } else { name = br.readLine(); if (name == null) { throw new IOException(filename + " expected name, reached end of file"); } } String type = br.readLine(); if (type == null) { throw new IOException(filename + " expected type of exercise, reached end of file"); } String time = br.readLine(); if (time != null) { throw new IOException(filename + " expected time of exercise, reached end of file"); } ActivityEvent activity = new ActivityEvent(); activity.day = day; activity.name = name; activity.typeOfExercise = type; activity.time = time; activities.add(activity); } return activities; } public void printActivities(List activities) { StringBuilder str = new StringBuilder("Day\tName\tType of Exercise\tTime\n"); int numActivities = activities.size(); int lastDay = -1; for (int index = 0; index < numActivities; index++) { ActivityEvent activity = (ActivityEvent)activities.get(index); if (activity.day != lastDay) { str.append(DAYS[activity.day]); } str.append('\t'); str.append(activity.name); str.append('\t'); str.append(activity.typeOfExercise); str.append('\t'); str.append(activity.time); str.append('\n'); } System.out.print(str.toString()); } </code></pre> <p>And then invoke everything for example:</p> <pre><code>List activities = loadActivities("somefile.txt"); // Do optional sorting, etc. here. printActivities(activities); </code></pre>
