Answer 1

I suspect you meant to use a comma instead of a period. A comma would separate two arguments, whereas what you have right now is not syntactically valid.

Answer 2

You might have meant to concatenate the KeySearch string with "line.txt", in which case you need to use + rather than a period. This can happen if you have your PHP hat on :)

Search obj = new Search(KeySearch + "list.txt");
