Java OCA OCP Practice Question 115

Question

Given the following class diagram,

which Java implementation most closely matches this structure? 

Diagram:
    Book 
+ price 
+ getRating() 

A.    public class Book { 
           public int numOfPages; 

B.    public class Book { 
           public String getRating() {return null;} 
      } /*from  www  . jav a 2 s. c om*/

C.    public class Book { 
           public int price; 
           public String getRating() {return null;} 
      } 

D.    public class Book { 
           void price; 
      } 



C.

Note

Option A does not compile because it is missing the closing bracket for the class.

Option D does not compile as void is not a valid type for a variable.

Options A and D are incorrect as they are missing the getRating() method.

Option A uses an abbreviation for price.

Option B is incorrect since it is missing the price attribute.

Option C is the correct answer as it properly defines the attribute price and method getRating().
