design-patterns - Concern 和 Responsibility 的区别(即 SRP 和 SoC 的区别)？

Question

SRP - each class should have just one responsibility ( ie reason to change)
Separation of Concerns is the process of breaking a computer program into distinct features that overlap in functionality as little as possible. A concern is any piece of interest or focus in a program. (Concern == feature of system. )

a) 据我了解，两者之间的唯一区别是 SRP 试图将职责 分成不同的类 和SoC 试图将关注点 分成不同的模块？!

b) 如果a) 下的假设是正确的，那么关注 和责任 之间的区别是什么(除了 em>责任存在于较低的抽象层次)？

谢谢

Answer 1

这就是我对它们的看法 - 同样的原则，通常在不同的抽象层次上引用。
