have the same (x, y) Section 8.4: Encapsulation 22. What is abstraction? How do objects provide abstraction? 23. What is the difference between the public and private keywords? What items should be declared private? 24. When fields are made private, client programs cannot see them directly. How do you allow classes access to read these fields' values, without letting the client break the object's encapsulation? 25. Add methods named setx and sety to the Point class that allow clients to change a Point object's x-and y-coordinates, respectively. 26. (You must complete Self-Check Problem 7 before answering this question.) Encapsulate the Name class. Make its fields private and add appropriate accessor methods to the class. 27. (You must complete Self-Check Problem 26 before answering this question.) Add methods called setFirstName, setMiddleInitial, and setLastName to your Name class. Give the param eters the same names as your fields, and use the this keyword in your solution. 28. How does encapsulation allow you to change the internal implementation of a class?
