I have a file named Songs.txt. Now i want to read the data in this file and store it in an ArrayList named SongList and sort it,using sort().
I have written the following program,but I am not able to proceed further.Please Help.

public class Song
public static void main(String[] args)
File file=new File("Songs.txt");
FileReader r=new FileReader(file);
BufferedReader b=new BufferedReader(r);
String line=null;
catch(IOException e)

If you are getting a string 'line' , which contains the song name, why don't you make an instance of ArrayList and add 'line' into it !!

And the call sort() method to sort them !!

It's simple, isn't it ?

If you haven't used any of the Collections classes before, you may want to work through the Java Tutorial chapter on that:
