ClassOne c1 = new ClassOne(); ClassOne c2 = new ClassTwo();
Which of the following method calls will cause an error? I c1.methodTwo();
II c2.methodTwo(); III c2.methodOne(); (A) None
(B) Ionly
(C) IIonly
(D) IIIonly

23. Consider the code segment
if (n == 1) k++;
else if (n == 4) k += 4;
Suppose that the given segment is rewritten in the form
if (/∗ condition ∗ /)
