Question

How many public class(s) (outermost) can be there in a java program?

(a) 1

(b) 2

(c) 3

(d) As required

The question was posed to me in exam.

My question is taken from Public Access Specifier in chapter Access Specifiers of Object Oriented Programming

Answer 1

The correct choice is (a) 1

To explain I would say: There can be only one public class in a java program. The public class name must match the name of file. And there can’t be more than one class with same name in a single program in same scope. Hence it is not possible to have more than one public class in java program.
