问题描述

我什么时候应该创建函数private，为什么它是个好主意?

When should i make a function private and why is it good idea?

推荐答案

当您不需要其他对象或类来访问该函数时，应该从内部调用它，则应创建一个函数private.课.

You should make a function private when you don't need other objects or classes to access the function, when you'll be invoking it from within the class.

坚持最低特权原则，仅允许访问绝对必要的变量/函数.不符合此条件的任何内容都应为private.

Stick to the principle of least privilege, only allow access to variables/functions that are absolutely necessary. Anything that doesn't fit this criteria should be private.
