Textbook Question
Chapter 8, Problem 7E
Derive a class ExaggeratingKid from SchoolKid, as described in the previous exercise. The new class should override the accessor method for the age, reporting the actual age plus 2. It also should override the accessor for the greeting, returning the child’s greeting concatenated with the words “I am the best.”

Suppose that class Child extends class Parent, and that Parent does not explicitly extend another class. Suppose also that Child has THREE constructors and Parent has TWO constructors. When creating a Child object, Child c = new Child(...), what is the minimum and maximum number of constructors being called in total?
Can the answer be in more classes then one where the classes will have relationships with other classes through the person
Develop a Class ( Standard Notation) for Student and Teacher. Also discuss if we can make a generlized class for these two.

- • Create two subclasses for checking and saving accounts.A checking account has an overdraft limit, but a savings account cannot be overdrawn. Draw the UML diagram for the classes and then implement them. Write a test program that creates objects of Account, SavingsAccount, and CheckingAccount and invokes their toString() methods.arrow_forwardPlease use "NewDate" class to solve this problem.arrow_forwardNow 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…arrow_forward
- Java - Write one or two sentences to describe the primary advantage of implementing an extended class. Your answer should use the word "inherited" at least once.arrow_forwardComplete the FoodItem class by adding a constructor to initialize a food item. The constructor should initialize the name (a string) to "None" and all other instance attributes to 0.0 by default. If the constructor is called with a food name, grams of fat, grams of carbohydrates, and grams of protein, the constructor should assign each instance attribute with the appropriate parameter value. The given program accepts as input a food item name, fat, carbs, and protein and the number of servings. The program creates a food item using the constructor parameters' default values and a food item using the input values. The program outputs the nutritional information and calories per serving for both food items. Ex: If the input is: M&M's 10.0 34.0 2.0 1.0 where M&M's is the food name, 10.0 is the grams of fat, 34.0 is the grams of carbohydrates, 2.0 is the grams of protein, and 1.0 is the number of servings, the output is: Nutritional information per serving of None: Fat: 0.00 g…arrow_forwardDefine a class named Employee. This class should extend the Person class from the previous question. The class should have a constructor, which takes the name, age, employer (String) and salary (int) as parameters (in that order). The first two parameters should be passed to the constructor of the superclass and the value of the last two parameters should be stored in instance variables. The class should define the methods, getSalary which returns the salary of the employee and getEmployer which returns the name of the employer. Any methods from the previous question that need to be overridden should be overridden! Use super and instanceof as appropriate. I.e., for the following methods you should be able to call the method in the superclass for specific situations (e.g. the compareTo method in the superclass can be called if you receive anything other than an Employee, and this also holds for the equals method). The toString method only needs to append details and as such can also…arrow_forward
- Please give the class diagram of the system and see if there is any problem in the operation of the classesarrow_forwardAnswer this qustion with refer to the part 1 and part 2 codes only an eample how to write in pic: In this and final part of the course work you are required to change the definition of the Item_in_Stock class to make it an abstract class and change the getItemCat(), getItemName() and getItemDescription() definitions to make them abstract methods. You are then required to design and implement three classes which are derived from Item_in_Stock class to fully demonstrate the concept of inheritance and polymorphism. Implementation of HP_Laptop class in part II should have given you an idea of inheritance and polymorphism. Three sub classes, one class against each category (Computers, Laptops and Accessories), should contain appropriate constructors, instance variables, setter and getters methods and overridden methods for getItemName(), getItemDescription() and get_Item_details() method. You should be creative and come up with your own ideas of sub-classes. Task 3.1.

The bug can only move for one unit of distance at a time, in the direction it is facing. The bug can also turn to reverse direction. For your design, create a UML Class diagram similar to Figure 5.5 on page 180 of the textbook. Note that you need to include the constructor in the methods section if you code a constructor. Bug will require a toString method to return the current position and which direction the bug is facing to the driver so it can be output.Hint: Remember that a horizontal line has a zero position in the middle with positive to the right and negative to theleft. Consider that a bug will land on the wire at some point before starting along the wire.Write an interactive test driver that instantiates a Bug, then allows the user to manipulate it with simple commands like Output (to see the position and direction), Move, Turn, Exit ... single letters work…arrow_forward
