Answer 1

Edit: If you want to do a search over a string which contains quotes/inverted commas in it already, you just need to take special care with your input. You can "escape" special characters to tell Java to treat them as normal characters. You do this by putting a backslash before them. In fact, more than just the quotes will be a problem - so will the < and > Check this link out for more information about escaping characters. So to search for your string, you would write:

boolean didContain = line.contains("\<div class=\"tupBin\"/\>");

If the input is read in by a scanner or stream, most likely it will be escaped for you already.
