private keyword vs no private keyword

Question

What is the use of the private keyword if everything, by default, is private?

public class A {
    object someObject;
    private object someOtherObject;
}

Wouldn't both of the above be private? If they're both private then why the need for the keyword itself?

Answer 1

Explicit use of the keyword clarifies the code, whatever the default is.

Avoid guesswork or the need for fact-checking on the part of code reader/maintainer, where possible.
