Hi Jonathan (at school),

You need to open the file and use the readLine method to read each line... put the following in a try..catch block

Code:
String filename = "somefile.txt";
FileInputStream fin =  new FileInputStream(filename);
DataInputStream myInput = new DataInputStream(fin);
while ((thisLine = myInput.readLine()) != null) {  // while loop begins here
   // inside the loop, you can either out.println(), or append to a string, or do whatever you want with each line
} // while

Send a message via AIM to Adam the Alien
Thumbs down Teacher won't help, or we wouldn't be here
Sammy,
The teacher of Canby High's Computer Programming class wanted us to search on the Internet for web pages or forums that could help us. I think he got sick of everybody asking for a lot of help.

Question Oh your teacher said to find out on your own
from my past experiences when a teacher says find out on your own it means he has no clue on how to do it? So i will help! Heres what u do since your cd's broken go to URL and search for a copy of the text book cd you can download. If you can't find one contact me. I should have more time this weekend to help you.
