Concept explainers
Repeat Exercise 1 for a credit card account instead of a credit card. An account represents the charges and payments made using 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.

- 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.arrow_forwardDesign 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.

- Draw the UML diagram for the classes and implement them. Write a test program that creates a Person, Student, Employee, Faculty, and Staff, and invokes their toString() methods.arrow_forwardThis is the question: Design and implement a class called Bug, which represents a bug moving along a horizontal wire. 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_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
- Create 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_forwardI need help in this question. Create a class diagram for an Account class( UML) using the following information: An Account has an identification number, a name and a cash balance. Activities on the account include credit, debit and inquire. An account can be created with a given id number and name, which cannot be changed after account creation. An account can also be created with a given id number, name and initial balance amount. If the initial balance amount is less than 0, balance is set to 0. When a given amount is credited to the account, the amount is added to the balance and the new balance is returned. When a given amount is debited from the account, the amount is deducted from the current balance and the updated balance is returned. Note that: only amounts greater than 0 can be credited. only amounts not greater than the balance can be debited. Otherwise, the balance remain unchanged. When inquiry to the account is made, the account id, name and current balance is…arrow_forwardWhat is an abstract class? Explain in detail with a coding example.arrow_forward
- Write 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_forwardWrite 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_forwardDesign and implement a class called Bug, which represents a bug moving along a horizontal wire. 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.

Hint: Remember that a horizontal line has a zero position in the middle with positive to the right and negative to the left. 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 just fine.…arrow_forward
