Abstract classes and interfaces may both be used to accomplish the goal of defining the behaviour of common objects.Which factors should you take into account when deciding whether to utilise an interface or an abstract class?
If the programmer doesn't declare any constructors for an extended class, what constructors will be inherited from the superclass? How does this inherited constructor initialize new instance variables that are not part of the superclass? Suppose that Vehicle is a class and Car is a new class that extends Vehicle. Write a description of which kind of assignments are permitted between Car and Vehicle variables. Suppose you write a new constructor for an extended class. Describe two different ways that the superclass's instance variables could be initialized within the constructor for the extended class.
For this problem you are to join the following classes into a hierarchy (use the UML diagrams from Module 2 to get started): Player - Super Class Archer - Subclass Barbarian - Subclass Cleric - Subclass Rogue - Subclass Warlock - Subclass If the parent class has the same attributes as the sub class then you can remove those attributes from the subclass. If the class is new for this module, please come up with 2 unique attributes of your choice, and 1 piece of functionality. If the sub classes are shown on the same level, then they share a parent class.
Write a java This class must implement the model in the following UML class diagram. Account -balance: double +Account(init_balance : double) +getBalance( ): double +deposit(amount : double) Diagram object’s description: balance holds the current balance of the bank account Account sets balance to init_balance get balance retrieves the current balance deposit adds the amount parameter to the current balance (Hint: “-“ indicates private and “+“ indicates public)
Why would someone declare a class as abstract? How might Interfaces help you to achieve multiple inheritance?
In order to qualify as a subclass of an abstract class, a class must offer concrete implementations for all of the abstract methods defined in the abstract parent class. Exactly how do you feel about this?
Abstract classes and interfaces may both be used to accomplish the goal of defining the behaviour of common objects.Which factors should you take into account when deciding whether to utilise an interface or an abstract class?
A subclass of an abstract class must provide concrete implementations for each of the parent class's abstract methods in order to be considered a subclass. What are your thoughts on this?
Java - If the programmer doesn't declare any constructors for an extended class, what constructors will be inherited from the superclass? How does this inherited constructor initialize new instance variables that are not part of the superclass?

In what kind of situation would you want to use an abstract class instead of a base class?
It is necessary for a subclass of an abstract class to implement all of the abstract methods that are defined for the parent class. Is there a mistake or is it accurate?
