Write code for the PQueue class and Explain the code.

Although the book focused on the normalization process only up to the Third Normal Form (3NF), there are actually four more commonly recognized normal forms – Boyce-Codd Normal Form (BCNF), Fourth Normal Form (4NF), Fifth Normal Form (5NF), and Sixth Normal Form (6NF). Research the uses of these other normal forms, then pick one to give a brief explanation of to the class. please pick one .

Deeper Class Design - the Square Class In this section, your job will be to write a new class that will adhere to the methods and data outlined in the "members" section below (said another way, your classes will implement a specific set of functions (called an interface) that we’ll describe contractually, ahead of time). These classes will all be shapes, with actions (methods) that are appropriate to shape objects, such as "getArea()", or "draw()". First we build a Square class that contains the following data and methods listed below, and then later, we will copy it to quickly make a Circle class. Note: when considering each data item below, think about what type of data would best represent the concept we’re trying to model in our software. For example, all shapes will have a coordinate pair indicating their location in a Cartesian coordinate system. This x and y pair may be modeled as ints or floats, and you might choose between the two depending on what the client application will...

In c++ Create a new project named lab11_1. You will be implementing three classes: A Clothing class, a Shirt class, derived from Clothing and third class of your choice that will be derived from Clothing. I have included the UML diagrams for Clothing and Shirt. You will need to make sure that the class you derive from Clothing is appropriate, meaning it makes sense that it would inherit from Clothing. In your driver file, I’d like to see a Shirt object created, as well as an object of the class type that you create. Set the class variable members to specific values, and then print. You can choose to override the output operator to make this easier, or you can implement a method named print(). Create a new project named lab11_2. Come up with your own base class, and derived class. No big specifications here on what you need to do (in terms of overloading operators, friend functions, static variables, composition, etc), but you have to make use of the base class members in the derived...

A for construct is used to build a loop that processes a list of elements in programming. To do this, it continues to operate forever as long as there are objects to process. Is this assertion truthful or false? Explain your response.

The code given below represents a saveTransaction() method which is used to save data to a database from the Java program. Given the classes in the image as well as an image of the screen which will call the function, modify the given code so that it loops through the items again, this time as it loops through you are to insert the data into the salesdetails table, note that the SalesNumber from the AUTO-INCREMENT field from above is to be inserted here with each record being placed into the salesdetails table. Finally, as you loop through the items the product table must be update because as products are sold the onhand field in the products table must be updated. When multiple tables are to be updated with related data, you should wrap it into a DMBS transaction. The schema for the database is also depicted. public class PosDAO { private Connection connection; public PosDAO(Connection connection) { this.connection = connection; } public void...

Complete the Course class by implementing the courseSize() method, which returns the total number of students in the course. Given classes: Class LabProgram contains the main method for testing the program. Class Course represents a course, which contains an ArrayList of Student objects as a course roster. (Type your code in here.) Class Student represents a classroom student, which has three fields: first name, last name, and GPA. Ex. For the following students: Henry Bendel 3.6 Johnny Min 2.9 the output is: Course size: 2 public class LabProgram { public static void main (String [] args) { Course course = new Course(); // Example students for testing course.addStudent(new Student("Henry", "Bendel", 3.6)); course.addStudent(new Student("Johnny", "Min", 2.9)); System.out.println("Course size: " + course.courseSize()); } } public class Student { private String first; // first name private String last; // last name private...

Explain memberwise assignment briefly.

Write a method for the farmer class that allows a farmer object to pet all cows on the farm. Do not use arrays.

If you have a class named Animal, give three examples of names of data fields (or attributes) you might expect this class to have.

B elow for each class you find a UML and description of the public interface. Implementing the public interface as described is madatory. There's freedom on how to implement these classes.The private properties and private methods are under your control.. There are multiple ways of implementing all these classes. Feel free to add private properties and methods. For each object, it's mandatory to create a header file (.h), implementation file (.cpp) and a driver. Blank files are included. The header should have the class definition in it. The implementation file should contain the implementations of the methods laid out in the header fine. And finally the Driver should test/demonstrate all the features of the class. It's best to develop the driver as the class is being written. Check each section to see if there are added additional requirements for the driver. Two test suites are included so that work can be checked. It's important to implement the drivers to test and demonstrate...

Hi, I am a bit lost on how to do this coding assignment. It would be great if someone could help me fill in the MyStack.java file with the given information. All the information is in the pictures. Thank you!
