从对象继承类

Question

I've found this declaration in the old project code:

public class Protokol:Object

Does it make any sense to inherit class from object? I am not sure if it was made on purpose or just a dirty code.

Answer 1

If you don't specify a class to derive from, then you automatically derive from object.

The code there is just being explicit. It's not wrong to explicitly derive from object, but it's not necessary to do so either as this is the default. Most people choose to omit the : object to keep the code clear.

Answer 2

不-每个类都从Object继承-您不必使其明确，但也不会造成伤害-取决于您。
