This is my code using File Reader and BufferedReader. I have a minor problem whereby i want to perform a method to check whether is there any additional data in every line in the text file. if yes, it will continue to display, if not, it will then stop. i know i could use hasNext but i couldn't get the condition right. could someone help me on this? thanks alot.

here is some pseudocode:

in each conditional (e.g. the while loops) you can add additional conditions:

and you can modify these additional conditions inside the loop



hope this helped....

If i want to insert my data into the database, must i use an array to do that? because i have to display out the data stored in eclipse and insert into the database at the same time. or i do not have to create array in order to perform this method? thanks alot!

what database are you using ?
assuming it is a "real" database (and not just a file) you probably want to use JDBC. this is a completely different story again...

i suggest you read up on JDBC, install a DB, try to make some simple examples and then get back to your original problem.

I m using db4o as my database. It's a open source database. So it doesn't require jdbc. Just add the external jar file. =) Thanks alot for your help

Non sequitur?

IIRC, db4o is an object database, so JDBC can't be used, even if one wanted to.
 
Don't get me started about those stupid light bulbs.
