What is the builder mode: If the definition on the Internet is relatively not easy to understand, we can make an analogy, when we need to build a complex object, for example, to build a car, then we need to make the various components of the car, such as wheels, engines, steering wheel, rearview mirror, etc. The components are then assembled and eventually assembled into a complete vehicle. the essence of the buil

1. Concept
Separates a complex build from its representation so that different representations can be created during the same build process. [Construction and representation separation, different representations are constructed in the same way]

1. Definition
Separates the construction of a complex object from its representation so that different representations can be created during the same construction process. Such a design pattern is called the builder pattern.
2. Applicable scenarios
1. When creating complex objects, algorithms should be independent of the components of the objects and their assembly methods. 2. When the constructor must allow different representations of the constru

Builder Mode: Separates the construction of a complex object from its representation, so that different representations can be created during the same construction process.
Basic IdeasThe construction of a product is composed of many complex components;Some details of these components are different, and the pr
Static factories and constructors have one common limitation: they do not scale well to a large number of optional parameters.When there are several required attributes and multiple optional attributes in a class, overlapping constructor mode, JavaBeans mode, or builder mode are used, but each has advantages and disadvantages.When there are many parameters, the client code in the overlay constructor mode is difficult to write and is still more difficu

For example, an e-mail message has a sender's address, a recipient's address, a subject, content, an appendix, and so on, which cannot be sent until the minimum recipient address has been assigned.
In some cases, it makes sense that some of the properties of an object must be assigned in a certain order. Another property cannot be assigned until a property is assigned a value. These circu

Builder mode (builder) can separate parts from their assembly process and create a complex object step by step.You only need to specify the type of the complex object to obtain the object, without having to know the specific structure details.
Under what circumstances will the builder mode be used?In my personal understanding, when we create an object, we need lo

I feel so uncomfortable. so I figured out if I co
Java builder Mode
When you need to input multiple parameters to create an object, we usually write different constructors according to the number of parameters, as shown below:
Public A (int ){}
Public A (int a, int B ){}
Public A (int a, int B, int c ){}
Different constructors are called based on different parameters, but when there are too many parameters,This method is not flexible enoughSo the method for dynamically passing parameters is implement
