I am writing a program where I am reading from a file, and the separator for my file data is a blank line, just whitespace, and I want to skip it whenever I get to it. My expression for reading from the file is String[] array = f.nextLine(" "). I tried putting conditions after this line, something like if(array.length == 0) or if (array == null), but it doesn't seem to get into these.

    Instead of describing your code, [edit] your question to include the code relevant to your question (a [mcve] would be even better). – azurefrog Jan 08 '18 at 18:57

For white space first trim the line:

line.trim();

And then check if it's null:

if (line.equals(""));

Then split it by using: 

String[] array = line.split (" ");

This will help!
