Defined in Gof:"Separating a complex build process from its object representation allows the same build process to produce different object behavior." ”The builder model can be divided into two steps to implement:1.

Let's review the basic concepts of design patterns:definitionthe construction of a complex object is separated from its representation, allowing the same build process to create different representations.Builders Hide how the product is assembled, so if you need to change the internal representation of a product, you just need to redefine a builder.Practical Range1. When creating complex objects, the algorithms should be independent of the components of the object and the way they are assembled.
