Question

public class A extends B { } class B { public B(String s) { } } Select ALL that apply The program has a compile error because A does not have a default constructor. 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. The program would compile fine if you add the following constructor into A: A(String s) {}

          public class A extends B {
}
class B {
public B(String s) {
}
}
Select ALL that apply
The program has a compile error because A does not have a
default constructor.
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.
The program would compile fine if you add the following
constructor into A: A(String s) {}

public class A extends B

class B
public B(String s)

Select ALL that apply

default constructor.
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.
The program would compile fine if you add the following
