. (9) If you have to do some awkward programming, at least you should put those code inside a class. (10) Whenever a class is found to be tightly bound to a class, it is necessary to consider whether the internal classes are used to improve coding and maintenance (see "Improving Code with internal classes" in chapter 14th 14.1.2). (11) Add comments as carefully as possible and generate your own program documentation with Javadoc annotation document syntax. (12) Avoid the use of "magic numbers",

Recommendations:For the refinement of the builder class, a tradeoff is needed. If these details are to be constructed for each specific subclass, then it should be added. Conversely, it is not necessary.In fact, the construction pattern is the gradual construction of the product, so the builders of the builder class in the building methods must be enough to be common to the various types of concrete builders
