Java OCA OCP Practice Question 2899

Question

Given: 

interface Printable { public void print(); }

Which will compile? (Choose all that apply.) 

A.  public class Shape implements Printable { public void print() { } } 

B.  public class Shape implements Printable { public void print(int x) { } } 

C.  public class Shape implements Printable {  
          public void print() { System.out.println("huhuhuhuh..."); }  
    } /*from  w ww .  ja  v  a  2 s  .  c o  m*/

D.  public abstract class Shape implements Printable {  
          public void print(int loud) { }  
    } 

E.  public abstract class Shape implements Printable {  
          public void print(int loud) ;  
    }  



A, C, and D correctly  implement the Printable interface.

Note

B is incorrect because Printable's no-arg print() method is not implemented.

E is incorrect because the overloaded print() method is not marked abstract, AND is not implemented.
