Analyze the following code: public class Test1 { public Object max(Object o1, Object o2) { if ((Comparable)o1.compareTo(o2) >= 0) { return o1; } else { return o2; } } }
A.
The program has a syntax error because Test1 does not have a main method.
B.
The program has a syntax error because o1 is an Object instance and it does not have the compareTo method.
C.
The program would compile if ((Comparable)o1.compareTo(o2) >= 0) is replaced by (((Comparable)o1).compareTo(o2) >= 0).
D.
b and c are both correct.
