Consider the following scenario: A chicken, eagle and duck are birds. A dog, cat, cow, and lion are animals. Human and Birds are also animals. Peas, carrots, and grass are plants. Chicken, duck, cow, and plants are edible. Draw a class diagram for the above scenario. You can use classes, inheritance, interfaces, and associations (including composition or aggregation) when needed. You shouldn’t use operations.

Make sure you know the difference between an abstract class and an interface and constructors.
Use java programming properties to write all the necessary classes and/or interfaces for a solution to the problem. Focus on class structure and interaction. You may implement your solution however you wish, but you will be graded on the appropriateness of your solution to the requirements. Note the use of capitalization and parentheses for clarification. You may use whatever constructors or additional methods you wish. Define a structure that can represent Animals. Animals have two behaviors; they can speak() and they can move(). By default, when an animal moves, the text ”This animal moves forward” is displayed. By default, when an animal speaks, the text ”This animal speaks” is displayed. A general Animal should not be able to be instantiated. Define two classes, Goose and Lynx, that are Animals. Both Goose and Lynx behave such that where “Animals” is displayed in speak() or move(), “goose” or “lynx” is displayed by the appropriate classes. Finally, any instance of Goose can fly(),…
Convert the UML class diagram above into a java code with the following conditions The methods in the Pet class are abstract. Create a class called test. The main() method in the test class should create three Cat objects and two Budgie The main() method should also create indirectly an object of the Pet class. Demonstrate polymorphism in your test

Create an abstract CardGame which contains a “deck” of 52 playing cards that uses a Card class that holds a suit and value for each Card object. It also contains an integer field that holds the number of cards dealt to a player in a particular game. The class contains a constructor that initializes the deck of cards with appropriate values (e.g., “King of Hearts”), and a shuffle() method that randomly arranges the positions of the Cards in the array. The class also contains two abstract meb. Create two child classes that extend CardGame. You can choose any games you prefer. For example, you might create a Poker class or a Bridge class. Create a constructor for each child class that initializes the field that holds the number of cards dealt to the correct value. (For example, in standard poker, a player receives five cards, but in bridge, a player receives 13.) Create an appropriate displayDescription() and deal() method for each child class.
Write the classes as shown in the following class diagram. Add a tester that asks the user for a cat, dog and a BigDog then call all of their methods. Note that Cat and Dog inherit from the abstract class Animal and BigDog inherits from Dog.
Write an abstract class, it can be anything well defined from the very basics.
Problem B Now we are going to use the design pattern for collecting objects. We are going to create two classes, a class AmazonOrder that models Amazon orders and a class Item that models items in Amazon orders. An item has a name and a price, and the name is unique. The Item class has a constructor that takes name and price, in that order. The class also has getters and setters for the instance variables. This is the design pattern for managing properties of objects. The setName() method should do nothing if the parameter is the empty string, and the setPrice() method should do nothing if the parameter is not positive. The class also has a toString() method that returns a string representation for the item in the format “Item[Name:iPad,Price:399.99]”. For simplicity, we assume an Amazon order can have at most 5 items, and class AmazonOrder has two instance variables, an array of Item with a length of 5 and an integer numOfItems to keep track of the number of items in the…
Why is multilevel inheritance allowed for interface but not allowed for class? You can use code example for establishing your reasonings.
NOTE: READ CAREFULLY Design a class named Person and a subclasses named Employee. Make Teacher a subclass of Employee. A Person has a name, address, and e-mail address. An Employee has an office, salary. A Teacher has office hours and a subject they teach. They also have a tenure status. Define the tenure status as a constant. The tenure status is either Senior or Junior, and is represented as an integer, where Senior is equal to 1, and Junior is equal to 2. Each class should have a Default constructor, and a constructor that accepts all arguments. There should be appropriate calls to the superclass within the constructors. Each class should also have getters and setters for each member variable. Each class should have a toString method. Note: You do NOT need to run this in a test program. Just create the classes as indicated above.
Abstract classes and interfaces may be used interchangeably to specify the behavior of objects.How do you know whether you need an interface or an abstract class?
Person and Customer Classes Write a class named (Person) with data attributes for a person’s name, address, and telephone number. Provide accessors/getters and mutators/setters for each attribute. Write a displayPerson() to print out the attributes of the Person. Next, write a class named (Customer) that is a subclass of the (Person) class. The (Customer) class should have a data attribute for a customer number, and a Boolean data attribute indicating whether the customer wishes to be on a mailing list. Provide accessors/getters and mutators/setters for each attribute. Write a display customer() to print out the attributes of the Customer. Demonstrate an instance of the (Customer) class in a simple program.
