(Inheriting Interface vs. Inheriting Implementation) A derived class can inherit “interface” or “implementation” from a base class. How do inheritance hierarchies designed for inheriting interface differ from those designed for inheriting implementation?

Overview Construct a hierarchy of classes representing savings and checking accounts as well as a means to ‘filter’ account objects. Account Classes Your solution will consist of 4 account classes as described below. It is your responsibility to define the exact relationship among those classes and translate that relationship into source code structure. There is a correct structure; the skeleton must be modified to reflect the correct relationships.  Account – represents a general account with basic operations such as deposit, withdraw, etc.  Savings – represents a savings account that must maintain a minimum balance.  Checking – represents a checking account that has no minimum balance (this means a zero balance).  CappedChecking – represents a checking account that disallows a balance above a particular maximum value. Linking Accounts A bank or credit typically allows a user the ability to link accounts together. That is, I might wish to link my checking account with my savings…

(JAVA) What is the benefit of an abstract class?   Group of answer choices   A) There is a guarantee that all classes that inherit from the abstract class have the methods and fields of the abstract class.   B) They cannot be instantiated, so you only need to write the code for the fields and methods that are common to all classes that extend it. You also need to initialize those fields in a constructor.   C) All choices are correct.   D) All classes that extend the abstract class will automatically inherit all the methods from the abstract classes without need to implement them again.

Instructions-Java Assignment is to define a class named Address. The Address class will have three private instance variables: an int named street_number a String named street_name and a String named state. Write three constructors for the Address class: an empty constructor (no input parameters) that initializes the three instance variables with default values of your choice, a constructor that takes the street values as input but defaults the state to "Arizona", and a constructor that takes all three pieces of information as input Next create a driver class named Main.java. Put public static void main here and test out your class by creating three instances of Address, one using each of the constructors. You can choose the particular address values that are used. I recommend you make them up and do not use actual addresses. Run your code to make sure it works.  Next add the following public methods to the Address class and test them from main as you go: Write getters and…
