Quick Abstract Method Question

[z_learning_tester]

I've read that a class with an abstract method becomes an abstract class.
That if only one method is abstract, then the class must also be so labled.

Does that make *all* methods of that class abstract?

Thanks!

No. You can have an abstract class with 10 concrete methods and one
abstract method. A concrete class derived from the abstract class only
needs to implement the single abstract method.
