How to read a text file from within an applet?

[Guest_imported]

I want to get Data from a text file to show in an applet .
what will be the syntax for that ..?

I also want to read data from database and write to text file whenever data in database changes.How it can be done by Java(Syntactically)

The reason for reading via a text file and not directly from database is "to save time from a querry processing each time an applet loads" is it justified?

Please give answers of my above 3 questions
Thanks in advance

There are very good examples of file i/o in Java for Students.

One proviso... an applet CANNOT read/write files on your local machine. This is to prevent rogue applets from destroying your hard drive. You need a free-standing Java application for that. Applets CAN read files off the internet, and (I need to test this myself) write them as well.

Assuming that the text file can be easily kept up to date (i.e. automated maintenance), and that the number of records in the text file is a small fraction of those in the database, I would think that reading a flat text file would be faster than running a query each time.
