BufferedReader readLine() issue: detecting end of file and empty return lines

Question

I want my program to do something when it finds the end of a file (EOF) at the end of the last line of text, and something else when the EOF is at the empty line AFTER that

Answer 1

Why not use

if (line.length()==0) {
    System.out.println("Found an empty line.");
}

Note: this will detect a blank line anywhere in the file, not just at EOF.
