What modifiers may be used with top-level class?-
public, abstract and final can be used for top-level class. In Java, a top-level class (i.e., a class that is not a nested or inner class) can have the following modifiers: public: The class can be accessed from any other class. (default, no modifier): If no access modifier is specified, the class is only accessible within the same package. So, the correct answer would be public and the default (package-private) modifier.
