You must try using CSV files instead of simple text files. Given that you have data that can be represented in a table with attributes and values, it is best to make it into a CSV file. You can use OpenCSV and make this process easy. Get the OpenCSV jar file and import it to your file. This will make your task easier. You can get OpenCSV from here: http://opencsv.sourceforge.net/
