Solved in 3 steps
- What is polymorphism in Java? It is when a program uses several different types of objects, each with its own variable. It is when a single variable is used with several different types of related objects at different places in a program. It is when a single parent class has many child classes. It is when a class has several methods with the same name but different parameter types.Please write code in JAVA Step 1: An Account class stores a current balance, and provides getBalance, deposit, withdraw, and toString methods in addition to at least one constructor. Add an account class to the project.Step 2: A CheckingAccount class extends the Account class and has additional attribute overdraft limit and additional method chequeDeposit. Implement the CheckingAccount class in the project. Make sure you add a constructor to the class.Step 3: Override the toString method in the CheckingAccount class to add the overdraft limit as well to the returned string.Step 4: A SavingsAccount class extends the Account class and has additional attribute interest rate and a method named addInterest to calculate and add the interest to the account. Implement the SavingsAccount class in the project. Implement the SavingsAccount class in the project. Make sure you add a constructor to the class.Step 5: Add a test class named AccountTester to the project and implement a main method in…Write the Movie class. The UML diagram of the class is represented below: 1. Implement the class strictly according to its UML one-to-one (do not include anythingextra, and do not miss any data fields or methods). 2. Implement a MovieTest class to test the class Movie you just created.• Create two Movie objects: one using the no-args constructor and one from theconstructor with all fields.• Print the contents of both objects. Please submit a screenshot. Hint: toString()method.
- Please follow the steps to complete JAVA PROGRAM Create a class, EmployeeException, that has the following attributes: name: String SSN: String Salary: double The methods required in this class are: A constructor with no arguments that sets the attributes at default values A constructor that passes values for all attributes Accessor, mutator, display method for each attribute. An example of a display method for an attribute is writeOutName(): void, in which you just display the name:System.out.println("Employee Name: " + name); An equals method that has an object of type Employee as argument, and returns true if two employees have the same name, salary, and SSN. Write a driver program for the Employee class that uses an array that can hold up to 100 employees (the array will be of EmployeeException type). However, the user should be free to enter as many employees as needed. The driver class should use two exception classes to signal the user that the SSN entered is not correct.…Write the class basics for an address class. Each class object should have its own street address, city, state and zip code. Be sure to include all the basic methods for this class. in java pleasein java Create a class for Student and implement all the below listed concepts in your class. Read lecture slides for reference. Class Name: Student 1. Data fields studentID name email majorDepartmentSelect proper datatypes for these variables. 2. Constructors – create at least 2 constructors No parameter With parametersSet id and name using the constructor with parameters. 3. Methods toString method : To print the details of the Student. Setter and getter methods 4. A static variable count : To keep the count of Student objects5. Visibility Modifiers: private for data fields and public for methods 6. Write some test cases in main method
- CODE IN JAVA Please look at the attached image for the information about the format the code should be in The code should be in two different .java files one with getFirstName, getLastName and getZipCode; the other file would be containing the main method Design and implement an application that reads a sequence of up to 25 pairs of names and postal (zip) codes for individuals. Store the data in an object of a class called “NameAndZip”, designed to store a first name (String), last name (String), and a postal code (int). Create a driver class called “NameAndZipList”. Assume that each line of input will contain two strings followed by an integer value. You will then create an object for each line read in and store that object in an array of NameAndZip objects. After the Names and Codes have been entered, print the list in an appropriate format to the screen using the toString method in the NameAndZip class. To test the program enter 3 names and codes.combines attributes and methods into one unit and hides its internal structure of objects. Select one: a.Information hiding b.Inheritance c.Polymorphism d.EncapsulationExplain through each question about Classes and Objects in Java. What is encapsulations and why is it useful? What is an instance method and how does it differ from the static methods we learned previously? What is a mutator method? What is an accessor method? What is a constructor in a Java class? What is an implicit parameter? Please provide an entire coding example to illustrate the answer.
- In Java programming (Lesson: Objects, Classes, and Constructors) Every class has a constructor and if we do not explicitly write a constructor for a class, the java compiler builds a default constructor for that class. False or True Please provide an explanation for the answer. Thank you!Define a java Name class with attributes: String firstname, middle name, lastname. Include the following methods: - A constructor with 3 parameters. Initialize the 3 member variables to the parameters being passed. Also, include the default constructor. - getter and setter methods for all attributes - override toString method Define a class called DebitCard. A debit card has a card number, Name and balance. a) Include a constructor with 3 parameters. Initialize the 3 member variables to the parameters being passed. Also, include the default constructor. b) Include getters/setters for all attributes. c) Add the following member functions: float inquireBalance() float depositCash(float amount) //increases the balance with amount boolean withdrawCash(float amount) // returns true if sufficient amount is available for withdrawal and decreases the balance by amount float interest(float rate) //calculates the interest rate incurred.
