 All statements of a method should belong to the same level of abstraction. If there is a statement which belongs to a lower level of abstraction, it should go to a private method which comprises statements on this level. Doing so will result in smaller methods. All statements of a method should belong to the same level of abstraction.

-Often the body of a loop can be extracted resulting in a separate private method. Loops should ideally contain a single statement (usually a method call).

 A further indicator for a missing method is the combination of a blank line, a comment and a block of code. In most of the cases the code block should go to a new private method. This also makes the comment obsolete as the new method carries a name which typically resembles the comment.  A further indicator for a missing method is the combination of a blank line, a comment and a block of code.
