The Builder Design Pattern helps us to slice the operations of building an object. It focuses on constructing a complex object step by step. It also enforces a process to create an object as a finished product. That means an object has to be massaged by some instructed steps before it is ready and can be used by others.
Generally, It allows you to encapsulate the complex create logic.
Builder pattern is very much like factory pattern. The key difference between a builder and factory is that a builder is useful when you need to do lots of things to build an object.
Builder design pattern helps to hide the complex logic in the builder class. Suppose we are developing a solution which constructs a large football field in different season as chosen by application users. We will create a builder class and pass the season info object in the builder class. Then the builder class is responsible construct the field according to seasons.
The intention is to abstract steps of construction of objects so that different implementations of these steps can construct different representations of objects.

构建器设计模式帮助我们对构建对象的操作进行切片。它专注于逐步构建一个复杂的对象。它还强制执行将对象创建为成品的过程。这意味着一个物体必须按照一些指导步骤进行按摩，然后才能准备好并可供其他人使用。
一般来说，它允许您封装复杂的创建逻辑。
构建器模式非常类似于工厂模式。构建器和工厂之间的主要区别在于，当您需要执行很多操作来构建对象时，构建器非常有用。

构建器设计模式有助于隐藏构建器类中的复杂逻辑。假设我们正在开发一个解决方案，根据应用程序用户选择的不同季节建造一个大型足球场。我们将创建一个构建器类并在构建器类中传递季节信息对象。然后建造者类负责根据季节建造场地。

当我们希望实例按特定顺序执行特定任务时，使用构建器设计模式，请参阅 wiki 构建器模式细节。

Builder Design Pattern is USED when we wants instance to perform specific tasks in specific order see wiki Builder pattern for details.
