Textbook Question

Chapter 3, Problem 1PC

Employee Class

Write a class named Employee that has the following fields:

name. The name field references a String object that holds the employee’s name.
idNumber. The idNumber is an int variable that holds the employee’s ID number.
department. The department field references a String object that holds the name of the department where the employee works.
position. The position field references a String object that holds the employee’s job title.

The class should have the following constructors:

A constructor that accepts the following values as arguments and assigns them to the appropriate fields: employee’s name, employee’s ID number, department, and position.
A constructor that accepts the following values as arguments and assigns them to the appropriate fields: employee’s name and ID number. The department and position fields should be assigned an empty string (" "),
A no-arg constructor that assigns empty strings (" ") to the name, department, and position fields, and 0 to the idNumber field.

Write appropriate mutator methods that store values in these fields and accessor methods that return the values in these fields. Once you have written the class, write a separate program that creates three Employee objects to hold the following data:

Chapter 3, Problem 1PC, Employee Class Write a class named Employee that has the following fields: name. The name field

The program should store this data in the three objects and then display the data for each employee on the screen.

In a shopping cart, there are various items, which can either belong to the category of household items or electronic items. The following UML diagram illustrates the relationship between items, household items, and electronic items. //Implementation Class public class ShoppingCart{ public static void main(String[] args){ final int MAX_ITEM = 50; Item cart = new Item[MAX_ITEM]; addItem(cart); // populate the item array printItem(cart); } } Considering that all the data definition classes and the implementation class are complete, which of the following Object-Oriented Programming (OOP) concepts do you need to use in the above context? i) Polymorphism ii) Method Overloading iii) Method Overriding iv) Dynamic Binding v) Abstract Class Explain, using course terminology, how you would use any of the above concepts to model the given scenario.

Answer this JAVA OOP question below: An Employee has a name, employee ID, and department. An Employee object must be created with all its attributes. The UML diagram is provided below: - name: String - employeeId: String - department: String + Employee(name: String, employeeId: String, department: String) + setName(name: String): void + setEmployeeId(employeeId: String): void + setDepartment(department: String): void + getName(): String + getEmployeeId(): String + getDepartment(): String + toString(): String A faculty is an Employee with an additional field String field: rank public class TestImplementation{ public static void main(String[] args){ Employee[] allEmployee = new Employee[100]; // create an employee object with name Tom Evan, employee ID 001 and department IST and store it in allEmployee // create a faculty object with name Adam Scott, employee ID 002, department IST and rank Professor and store it in allEmployee } }

Please answer this JAVA OOP question that is given below: An Employee has a name, employee ID, and department. An Employee object must be created with all its attributes. The UML diagram is provided below: - name: String - employeeId: String - department: String + Employee(name: String, employeeId: String, department: String) + setName(name: String): void + setEmployeeId(employeeId: String): void + setDepartment(department: String): void + getName(): String + getEmployeeId(): String + getDepartment(): String + toString(): String A faculty is an Employee with an additional field String field: rank Assuming the Employee class is fully implemented, define a Professor class in Java with the following: A toString() method that includes both the inherited attributes and the specialization
