11. public interface Status {

12.   /* insert code here */ int MY_VALUE = 10;

13. }

Which three are valid on line 12? (Choose three.)

A. final

B. static

C. native

D. public

E. private

F. abstract

C. protected

 

Ans: A B D

 

解說:

Interface中的資料變數隱含為final、static及public

final是因為介面是規格，規格是不能改的

static因介面不能具現化，必然是類別的型態

public則是介面本為公開性質
