Why is it required to invest extra time and effort to prevent overly linked classes while programming in Java (and object-oriented programming in general)? Why is it vital to avoid having classes that are too closely related to one another? What are the top three explanations for this?
We would like to design a software system so that ...
we can easily add new functionality without large changes in our software design or code-level implementation.
we can easily add or remove easily new functionality without large changes in our software design or code-level implementation.
we can easily modify the existing functionality without large changes in our software design or code-level implementation.
we can easily use the software system in different scales, i.e., create more or less instances of classes.
we can do all of the above.
When can the occurrence of dual inheritance lead to uncertainty? Is there any way to fix this issue? Just what are virtual base classes? Where does their value lie, exactly?

- A lot of these patterns feel very powerful and useful for abstracting and re-using code.
