Create the above hierarchy as follows” Create Book class having above attributes provide getter, setters and toString() method also make netProfyt() which returns profit by (salePrice- costPrice), and getTax() method which calculates 30% tax on the profit gain above. Now create EBook which extends Books class and have sizeMB and downloadSite as attributes provide a constructor which will set values of above attributes and attributes of parent class as well, Provide getters /setters also. Now rewrite the getTax() method which will calculate tax on profit 30% + Rs 200 (per EBook ).

1. Create 2 interfaces: BankInterface and PetInterface. BankInterface contains only 1 abstract method: accountType() which does not return anything and takes 1 String argument: accType. PetInterface contains only 1 abstract method: petType() which does not return anything and takes 1 String argument petType. 2. Create an abstract class named Student. This class contains 2 instance variables, 1 constructor, and 2 abstract methods. a. Instance variables: stId and stName (Use must use appropriate data type.) b. A 2-argument constructor that will be called from its subclass (the concrete class) to load 2 instance variables of this level during the creation of an object in its subclass. c. 2 abstract methods: getStId and getStName.. Each of these methods, when sub classed into concrete ones, should return the respective values of the instance variables stId and stName. d. At this level you should do something to get the object state at this level. 3. Create a concrete class named…

Create a class of Dog, some of the differences you might have listed out maybe breed, age, size, color, etc.  Then create characteristics (breed, age, size, color) can form a data member for your object. Then list out the common behaviors of these dogs like sleep, sit, eat, etc. Design the class dogs with objects and methods.
JAVA please help Design a class named Sandwich with data fields for description and price. Include a constructor that requires arguments for both fields and a method to display the data (example value for description is chicken). Create a subclass named DeliverySandwich that inherits from Sandwich and has a delivery fee and a delivery address as additional fields. The description, price, and delivery address are required as arguments to the subclass constructor. The delivery fee should be set to $3 if the sandwich ordered costs more than $15; otherwise it should be set to $5. Write an application that instantiates at least two objects of each type and displays their state (data).

Design a class named octopus that holds attributes for an octopus named weight and color. Include methods to set and get each of these attributes. Create the class diagram and write the class pseudocode that defines the class. Create a small program that declares two octopus objects and set the octopus's name weight and color attributes the program must also output each octopus's name weight and color after they are set. Please write out the pseudocode. I have a hard time with this.
