1: Intention: separates the construction of a complex object from its representation, so that different representations can be created during the same construction process.
2: Motivation
3: Applicability:

Introduction:For Android, the Builder design mode may be rarely used in our development, but we may have seen that AlterDialog. Builder is a Builder mode. So what is the builder model? Let's take a look at its

Builder mode is the creation mode, creating a product that hides the creation process, using a combination of methods, by the conductor (director) to determine the construction processpublic interface Builder {void Buildparta (); void Buildpartb (); void Buildpartc ();}public class Builderimpl implements Builder {@Overridepublic void Buildparta () {System.out.pri
Builder mode Definition: separates the construction of a complex object from its representation so that the same build process can create different representations.The builder pattern is a step-by-step creation of a complex object that allows the user to build them only by specifying the type and content of the complex objects. The user is not aware of the specifics of the build internals. The
The builder pattern is somewhat similar to the previous abstract factory pattern, but more powerful than the abstract factory pattern, the builder pattern can be seen as two parts, one builder, and the other is that the basic idea of Director,builder is the abstract factory, While the director exists to make the use of
Idea: Since the interstellar picture is made up of several parts: the map (the terrain and the minerals), the building, the troops. Then we think of them as parts, assembled to be the final product (the whole picture).

Because a complex object has many components, such as a car, a wheel, a steering wheel, an engine, and various small parts, how can we assemble these components into a car, this assembly process is long and complex. In this case, in order to hide implementation details from the outside during the construction process, you can use the

Builder mode
Separating the construction of a complex object from its representation allows the same build process to create different representations.

C ++ Builder is a high-performance visual integrated development tool launched by Borland. It not only integrates most development tools, the C ++ Builder development tool also provides visual Form Designer, object observer, control board, Engineering Manager, integrated editor and debugger.

Key points of the builder mode:
The builder mode is mainly used"Build a complex object in steps ". In this case, "step-by-step" is a stable multiplication, while all parts of complex objects change frequently.
The builder mode mainly dealsFrequent demand changes for "various parts of complex objects. ItsDisadvantage:It is difficult to cope with changes in the dem

the created object to be inconsistent in its state. This will appear in multithreaded programs. For example, Cocacola.setsodium (35); Before executing this code, the object CocaCola has already been used by other threads, which results in the use of a CocaCola object that is not in the correct state. simply put, the object is created, and the code that sets the state of the object is not atomized. --------------------------------------------------------------------------------------------------

The builder model separates the internal representation of a product from the product generation process, enabling a build process to generate a product object with a different internal representation.

There are many examples of builder in life, and personally feel that college life is the best experience of a builder model: to complete a university education, the university education process is generally divided into 4 semesters, so no study can be seen as a part of the construction of a complete university education process, Each person has a different final result after the 4-year (4-phase) build proce
