String .equals opposite [closed]

It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, visit the help center. 开发者_如何学PythonClosed 11 years ago.

I have this line of code:

if(command.equals("e") || command.equals("d")) {
   //statements
}

---

The opposite of

(command.equals("e") || command.equals("d"))

is

(!(command.equals("e") || command.equals("d")))

or in a different form

(!command.equals("e") && !command.equals("d"))
