Textbook Question

Chapter 12, Problem 12.29PE

(Rename files) Suppose you have several files in a directory named Exercisei_j, where i and j are digits. Write a program that pads a 0 before j if j is a single digit. For example, a file named Exercise2_l in a directory will be renamed to Exercise2_01. In Java, when you pass the symbol * from the command line, it refers to all files in the directory (see Supplement III, V). Use the following command to run your program:

java Exercise12_29 *

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
