Java OCA OCP Practice Question 2665

Question

Choose the correct statement about the following code: 

1: public interface Printable { 
2:    void print(); 
3: } 
4: interface Displayable { 
5:       public abstract Object get(); 
6: } 
7: abstract class Shape implements Printable, Displayable { 
8: }
  • A. It compiles without issue.
  • B. The code will not compile because of line 2.
  • C. The code will not compile because of line 4.
  • D. The code will not compile because of line 5.
  • E. The code will not compile because of lines 2 and 5.
  • F. The code will not compile because the class Shape doesn't implement the interface methods.


A.

Note

Although the definition of methods on lines 2 and 5 vary, both will be converted to public abstract by the compiler.

Line 4 is fine, because an interface can have public or default access.

Finally, the class Shape doesn't need to implement the interface methods because it is marked as abstract.

Therefore, the code will compile without issue.
