Analyze the following code: public class A{ public static void main(String args[]) { B b = new B(); b.i= b.i++; } } class B { private int i; B() { } } The program has a compilation error because i' variable is not visible inside method 'main! The program has a compile error because the 'B' class has a non-public constructor. The program compiles and runs fine. The program compiles, but has a runtime error because 'i' has no initial value
