Few years ago I was looking at legacy code that was developed by offshore team (what could go wrong,right) and I see small utility method that looks like this:

public boolean isEmptyNotEmpty(String s) {
boolean empty=false;
If(s==null) {
empty =true;
}
If(s.equals("")) {
empty = true;
}
return empty;
}

Thinking in myself: was he/she paid per line the line of code??!?!

Up to this date that was the worst part of the code that I encountered....
