ByteBrawl - Quiz - Abstract Classes

Abstract classes can be instantiated directly.

Abstract classes can contain both abstract and concrete methods.

A class can extend multiple abstract classes.

Abstract classes cannot have constructors.

There will be a compile-time error because the method is not implemented.

It depends on whether the subclass is also abstract or not.

The program will compile, but will throw a runtime error when trying to instantiate the subclass.

The abstract methods will be ignored in the subclass.

They are implicitly public, static, and final.

They are generally unaffected, so you can still have instance/static, etc.

They are private and can only be accessed within the abstract class.

They are protected and can be accessed by subclasses only.
