Answer this Java OOP question below:
Discuss the challenges and benefits of using multiple levels of inheritance in a class hierarchy. How can deep inheritance structures impact the maintainability and readability of code?
Answer the Java OOP question below:
Explain the relationship between a superclass and a subclass. How do the principles of encapsulation and abstraction play a role in this relationship? In your experience, how do you decide what should be included in a superclass versus a subclass? Share an example where a well-defined superclass-subclass hierarchy improved your code.
1.) Consider the problem of determining whether a DFA and a regular expression are
equivalent. Express this problem as a language and show that it is decidable.
ii) Let ALLDFA = {(A)| A is a DFA and L(A) = "}. Show that ALLDFA is decidable.
iii) Let AECFG = {(G)| G is a CFG that generates &}. Show that AECFG is decidable.
iv) Let ETM {(M)| M is a TM and L(M) = 0}. Show that ETM, the complement of
Erm, is Turing-recognizable.
