问题:
1. interface A { public void aMethod(); }
2. interface B { public void bMethod(); }
3. interface C extends A,B { public void cMethod(); }
4. class D implements B {
5. public void bMethod() { }
6. }
7. class E extends D implements C {
8. public void aMethod() { }
9. public void bMethod() { }
10. public void cMethod() { }
11. }
What is the result?()
A . Compilation fails because of an error in line 3.
B . Compilation fails because of an error in line 7.
C . Compilation fails because of an error in line 9.
D . If you define D e = new E(), then e.bMethod() invokes the version of bMethod()defined in Line 5.
E . If you define D e = (D)(new E()),then e.bMethod() invokes the version of bMethod() defined in Line 5.
F . If you define D e = (D)(new E()), then e.bMethod() invokes the version of bMethod() defined in Line 9.
