Question

I have a method that read the next line in a txt file and does something. I have another method that needs to check for EOF as well. The two methods are called receptively within a loop.

method 1:

trace = br.readLine();
   if (trace==null)
       break; // end of file

method 2:
I need to check for EOF without using the same technique. Otherwise, it would increment the ptr used for readLine…

Is there any way to accomplish this?

Thanks

Answer 1

You can use

 Scanner sc = new Scanner (file);

and read

 while (sc.hasNext ())

Scanner has a

  sc.readLine (); 

method.
