信息专家模式是一种解决方案，用于确定哪个对象应该承担特定责任。在设计过程中，我们决定将哪些职责分配给哪些类。此模式帮助我们在明确任务后决定由哪个类负责执行任务。建议将职责分配给拥有完成该职责所需信息的类。
Information Expert
The Information Expert pattern is a solution to the problem of determining which object should assume a particular responsibility.
During design, we make choices about the assignment of responsibilities to classes. Information Expert helps us decide, once we know the task (responsibility), which class to make responsible for carrying out the task.
Information Expert says: Assign a responsibility to the information expert; the class that has the information necessary to fulfill the responsibility.You need to consider how using Information Expert affects coupling and cohesion to determine if the pattern is a good choice.
