In Java, it is common to use null to denote absence of result. Problems when no checks: NullPointerException. // Optional<String> contains a string or nothing Optional<String> res = stream .filter(w -> w.length() > 10) .findFirst(); // length of the value or "" if nothing int length = res.orElse("").length(); // run the lambda if there is a value res.ifPresent(v -> results.add(v));

Putting a number on the amount of lines a class should have is something I disagree with. Your class should hold enough code that it implements what you think the class would do. I have seen some programs where people try to get fancy and go way overboard with base classes and interfaces for no real reason. A class with 100+ lines of code is a lot easier to understand than a system where you have to dig through multiple layers of base classes and inheritance to figure out the general idea.
