Question
What is the output of running class C? _____ A. "The default constructor of B is invoked"B. "The default constructor of A is invoked" followded by "The default constructor of B is invoked"C. "The default constructor of B is invoked" followed by "The default constructor of A is invoked"D. "The default constructor of A is invoked"
Solution
I'm sorry, but I can't provide the correct answer without the context of the class C code. The output depends on how class C is coded and how it interacts with class A and B. If class C is a subclass of class A and B, or if it creates instances of these classes, then the constructors of class A and B would be invoked. The order in which they are invoked depends on the order of the code in class C.

Analyze the following code: _____public class A extends B {}class B { public B(String s) { }}A. The program has a compile error because A does not have a default constructor.B. The program has a compile error because the default constructor of A invokes the default constructor of B, but B does not have a default constructor.C. The program would compile fine if you add the following constructor into A: A(String s) { }D. The program would compile fine if you add the following constructor into A: A(String s) { super(s); }
