Question 2

Given the following classes and their objects:

class C1 {};
class C2 extends C1 {};
class C3 extends C1 {};

C2 c2 = new C2();
C3 c3 = new C3();

Analyze the following statement:

c2 = (C2)((C1)c3);

◦ c3 is cast into c2 successfully.
◦ You will get a runtime error because the Java runtime system cannot perform multiple casting in nested form.
◦ You will get a runtime error because you cannot cast objects from sibling classes.
◦ The statement is correct.
