Question
Which of the following is an incorrect statement about interfaces?OptionsInterfaces 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.Interfaces are specified public if they are to be accessed by any code in the program.
Solution
The incorrect statement about interfaces is: "Interfaces are specified public if they are to be accessed by any code in the program."
This is incorrect because the access specifier of an interface does not determine whether it can be accessed by any code in the program. In Java, an interface is accessible to any class that can access the package in which the interface is declared. The public keyword only determines whether the interface can be accessed outside its package.

Which of the following statements about interfaces in Java is correct? Select one: The methods specified in the interface have a body enclosed by curly brackets. They are defined with the keyword "interface." The syntax is similar to that of a class, with the difference that no methods are abstract. They are defined with the keyword "abstract."
Which of the following statements is wrong? Select one: With the exception of constants, no attributes may be specified in interfaces. The class must implement at least one method for each interface. The class must implement all methods for each interface or it must be declared abstract. With the help of the keyword "implements" a class can indicate which interfaces it implements.
