What are the the two parts of an ADT? Which part is accessible to a user and which is not? Explain the relationships between an ADT and a class; between an ADT and an interface; and between an interface and classes that implement the interface.

public i nterface Comparabl e { I IN compare To(Object obj) ;

 }

Do you think class String implements interface Comparabl e? Provide a reason for your answer
