9. What is the result of compiling the following code?  
import java.io.*; 
class MyExp {  
      void MyMethod() throws IOException, EOFException { 
            //............// 
      }  
}  
class MyExp1 extends MyExp { 
       void MyMethod() { 
          //..........// 
       }  
}  
public class MyExp2 extends MyExp1 {  
        void MyMethod() throws IOException { 
             //.........// 
        }  
}  
A) Compile time error  
B) No compile time error  
C) Run-Time error 
D) MyMethod() cannot throw an exception in MyExp2 class  

Answer given:A,D
for D, in MyMethod() in MyExp2 class, Unchecked exception can be throw, even in method declare, it can throws Unchecked exception.
I think if D says: MyMethod() cannot declare IOException exception in MyExp2 class , then it would be correct.

I agree with you here. Java insists that an overriding method can not throw a checked exception not thrown by the method it is overriding. It can however throw runtime exceptions.
