Thinking: the size of the code block is the code out of a method or reconstruct or one designed to measure whether a method factors in the design of it?

Is, however, a fundamental factor is the design and function of a separate division methods (implementation) block represents, in a way that is timely only one line of code, but this method
can be a very independent representatives ( independent) function, then the code should be organized into a separate method, instead of saying less code (even on one line), so I do not smoke
