Question: Given the information for the following, determine whether they will result: Always compile, sometimes compile, or does not compile. public interface A public class B
Given the information for the following, determine whether they will result: Always compile, sometimes compile, or does not compile.
public interface A
public class B implements A
public abstract class C
public class D extends C
public class E extends B
Each class have been initialized, but it is not clear what they have been initialized to:
A a = new...
B b = new...
C c = new...
D d = new...
E e = new...
The following methods are included:
interface A specifies method void methodA()
class C has the abstract method void methodC()
| Code: | Always Compile, Sometimes Compile, or Does Not Compile? |
| a = new B(); |
|
| d = new C(); |
|
| b.methodA(); |
|
| e.methodA(); |
|
| c = new C(); |
|
| (D)c.methodC(); |
|
