to split strings up into their constituents according to a regular
expression, you can use the split method of class String. Here are the
details:

http://java.sun.com/j2se/1.4.2/docs/api/
http://java.sun.com/j2se/1.4.2/docs/api/java/lang/String.html#split(java.lang.String)

So, in your case, you have a string "record", which is a line
consisting of space separated words. The regular expression is thus 
" ", or to catch multiple spaces, " +".

The split operator returns a String[], pseudo-code:

  String[] parts = record.split(" +");

hope this helps,
dominik

ps: I didn't want to spoil your programming pleasure, so I didn't send
the whole modified code... :-)
