Sorting a list

Question

I have a list of clients that is ever-changing. I would like to have a way to edit a text file and have that populate my client list page on my website. Is that possible with Java? I was told that Java is the only way to do that. I would appreciate any help you would have
Thank you very very much.

Answer 1

parse in the file, and for each line (i'm assuming there is one data entry per line? if not, youll have to do some string manipulation) add the line into an ArrayList. After you are done reading, call this:
Collections.sort(list);
and then your ArrayList will be sorted.
For the file reading in try:
ArrayList list = new ArrayList();
BufferedReader in = new BufferedReader(new FileReader(new File("path to your file"))));
String line = in.readLine();
while(line != null) {
list.add(line);
in.close();
Collections.sort(list);
//read the sorted list now
