In a C++ program, create a Student class, where attributes associated with each student are name, registration number, father name, degree and department. All attributes should not be accessed directly. One can view the details of all students. Note student attributes can not be changed by anymeans after initialization. (Hint use constant objects)
Write three static comparators for the any Point2D data type , one that compares points by their x coordinate, one that compares them by their y coordinate, and one that compares them by their distance from the origin. Write two non-static comparators for the Point2D data type, one that compares them by their distance to a specified point and one that compares them by their polar angle with respect to a specified point.
The following java function executes an SQL query based on the inputs from the combo boxes and text box from the screen shown and is supposed to return a list of items that match the query. The input string is a string of the field, operator and criteria text from the boxes separated by commas. However, the method is not currently functional and must be modified to enact the query. Modifiy the function so that it works properly. An image of the database schema has also been attached as well as the product class.
public List<Product> getProductByCriteria(String criteria) {
if (openConnection()) {
try {
List<Product> items = new ArrayList<>();
Product temp = null;
String[] fields = criteria.split(",");
String query = "SELECT * FROM products WHERE " + fields[0] + fields[1] + fields[2];
stmt = conn.prepareStatement(query);
ResultSet rs = stmt.executeQuery();

- Create three static comparators: one that compares points based on their x, y, and distance from the origin; the other two compare points based on any Point2D data type. For the Point2D data type, create two non-static comparators: one that compares objects based on how far they are from a given point, and the other that compares objects based on how far they are from a given point polarly.arrow_forwardWe wish to implement a system that allows the management of Employees and Students. As a first step. you need to implement the above UML diagrams Notes: . ZOOM . PERSON, EMPLOYEE and STUDENT should be public static constants The no-arg constructor will initialize ID, firstName and lastName to their respective null values. It will set personType to PERSON, and sortorder to LAST_NAME The overloaded constructor will assign each parameter to its respective field. sortorder will also be set to LAST_NAME toString() will output type, ID, firstName and lastName, all tab separated. This is an override method equals() will compare if the current object and the parameter contain the same values. This is an override method compareTo() compares the current object and the parameter. This is an override method. It will be used to sort objects Needs the Comparable interface O Will only compare fields depending on the sortorder. For example, if the sortorder is TYPE, it should then compare the…arrow_forwardComplete the code to create a polymorphism situation.arrow_forward
- Consider the following scenario: you are asked to create a Java class MetaDisplay that contains a static void printTable(String r) method. The method takes a relation name r as input, executes the query "select * from r," and prints the result out in tabular format with the attribute names displayed in the table's header; the attribute names are displayed in the table's header.

Matrix is to be stored in a class object which should be constructed using a constructor dynamically by asking rows and columns to the user.arrow_forwardUsing the scenario of Object oriented programming Q1 Write a program that defines a class with a data member to holds a “serial number” for each object created from the class. That is, the first object created will be numbered 1, the second 2, and so on. To do this, you’ll need another data member that records a count of how many objects have been created so far. (This member should apply to the class as a whole; not to individual objects. What keyword specifies this?) Then, as each object is created, its constructor can examine this count member variable to determine the appropriate serial number for the new object. Add a member function that permits an object to report its own serial number. Then write a main() program that creates three objects and queries each about its serial number. They should respond I am object number 2, and so on.arrow_forward

Base your design on the following business rules: A salesperson may sell many cars, but each car is sold by only one salesperson. A customer may buy many cars, but each car is bought by only one customer. A salesperson writes a single invoice for each car he or she sells. A customer gets an invoice for each car he or she buys. A customer may come in just to have his or her car serviced; that is, a customer need not buy a car to be classified as a customer. When a customer takes one or more cars in for repair or service, one service ticket is written for each car. The car dealership maintains a service history for each of the cars serviced. The service records are referenced by the car’s serial number. A car brought in for service can be worked on by many mechanics, and each mechanic may work on many cars.
