Question
Select the correct answerWhich of the following is an incorrect statement about interfaces?OptionsInterfaces are specified public if they are to be accessed by any code in the program.Interfaces specifies what class must do but not how it does.All variables in interface are implicitly final and static.All variables are static and methods are public if interface is defined public.
Solution
The incorrect statement about interfaces is: "All variables are static and methods are public if interface is defined public."
This is incorrect because in an interface, the variables are always implicitly static and final, and the methods are always public, regardless of whether the interface is defined as public or not. The accessibility of the interface (public or not) does not change these properties of the variables and methods within it.
