Hi All,
How should I differentiate between End of File and blank space between lines in a file. Below is a sample input for the program:
a b c
d e f
i j k
l m nMy following code is able to read only till 'd e f'.
Here is the code:
        Scanner lscFileRead = new Scanner (ffInputFile);
        while ((lsLn =  lscFileRead.nextLine()) != null)
        }Please help me out.

        while ((line = lscFileRead.nextLine()) != null)
            System.out.println("[" + line + "]");
        is.close();

@OP: You should be using Scanner#hasNextLine() to determine if you are at EOF.
