Repeat Exercise 1 for a collection of coins instead of a credit card.
Design a class to represent a credit card. Think about the attributes of a credit card; that is, what data is on the card? What behaviors might be reasonable for a credit card? Use the answers to these questions to write a UML class diagram for a credit card class. Then give three examples or instances of this class.

- Design a UML diagram to represent class called damConstruction, to implement the properties of a water dam construction. Your class should have the instance variables to store the length (in meters), width (in meters), depth (in meters), the rate (in litters per minute) at which the water is filling the dam, and the rate (in litters per minute) at which the water is draining from the dam. Add appropriate constructors to initialize the instance variables. Also add member functions to do the following: determine the amount of water needed to fill an empty or partially filled dam; determine the time needed to completely or partially fill or empty the dam; add or drain water for a specific amount of time: 1. Following the UML diagrams you designed in 1., code the class.arrow_forwardDesign a UML diagram to represent class called damConstruction, to implement the properties of a water dam construction.

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
- 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. All your programs will be modular. It will have the main() method that is executed first. Submit code that has no syntax error. And test your code, so as to not have logic errors. Each program must contain your name in the comments section and the date you created the code.arrow_forwardBelow we have class diagrams with three classes for a simple java based parking management class. Use the classes below to write java code for classes :a parking observer class (that implements an observer pattern) , a transaction manager class and a parking lot class(subject to the observer). Use the class diagram and java class to implement it. You should use an observer pattern to implement your code.The main goal is to implement the following - Once a car enters (in an entry-scan only lot) or leaves (in an entry-scan and exit-scan lot), then the ParkingObserver will be updated, and then can register the charge with the parking system via the TransactionManager’s park() methodarrow_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
- What is an abstract class? Explain in detail with a coding example.arrow_forwardWrite a class named Person with data attributes for a person’s name, address, and telephone number. 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 numberand a Boolean data attribute indicating whether the customer wishes to be on a mailing list. Demonstrate an instance of the Customer class in a simple program.arrow_forwardDesign and implement an object-oriented program for displaying a deck of cards. Each card will have a value ranging in order from 1 for an ace, 2 for a two, and so on up to and including 11 for a jack, 12 for a queen, and 13 for the king. The focus of the exercise is to create three classes that represent a card, deck, and hand using composition.arrow_forward

BMS contains 2 classes: Bookand BookList. The Book class has the following attributes: code: a String object, that hold the book’s code. title: a String object, that hold the book’s title. qua: int variable, that hold the number of books with the same code in the library. price: a double variable, that hold the book’s price. The BookList class contains only one data member: ArrayList<Book> t. When running the program display the menu as below:1. Input & add book(s) to the end.2. Display all books.3. Search a book for given code.4. Update the book’s price for given code.5. Find the (first) max price value.6. Sort the list ascendingly by code.7. Remove the book having given code.8. Load data from file.0. Exit.Notes:(1) The book’s code must be unique in the list.(2) Display all books in format (code, title, quantity, price).(5)…arrow_forwardCreate an UML diagram to help design the class in the following Java program description. Write Java code for a Baby class. A Baby has a name of type String and an ageof type integer.Supply two constructors: one will be the default constructor, that just setsdefault values for the name and age; the second constructor will take twoparameters, a string to set the name and an integer to set the age. Also, supplymethods for setting the name, setting the age, getting the name and getting theage.The class should not contain I/O methods; input of values to the instancevariables must be done with a set method or constructor, output of values fromthe instance variables must be done with get methods. The set method for thename instance variable should ensure that the input is not empty or containwhitespaces (otherwise set a default value). The set method for the ageinstance variable should validate the input to be between 1 and 4 inclusive(otherwise set a default value).Give Java code for an…arrow_forward
