If we do not specify modifier for a class, what does it take by default?Select one:abstractprivatefinalpublic

When we do not specify a modifier for a class in Java, the default modifier that is applied is package-private. This means that the class is accessible only within classes in the same package.

Here's a brief explanation of the other options:

1. abstract - This modifier is used to declare a class that cannot be instantiated on its own and must be subclassed.
2. private - This modifier restricts access to within the class itself, which is not applicable for top-level classes.
3. final - This modifier prevents a class from being subclassed.
4. public - This modifier allows the class to be accessible from any other class in any package.

Since none of the options provided (abstract, private, final, public) accurately represents the default modifier in this context, the answer is that a class has a default package-private access level when no modifier is specified.

Final Answer

The default modifier for a class when none is specified is package-private.
