This is the question I am stuck on - A. Create a CollegeCourse class. The class contains fields for the course ID (for example, CIS 210), credit hours (for example, 3), and a letter grade (for example, A). Include get and set methods for each field. Create a Student class containing an ID number and an array of five CollegeCourse objects. Create a get and set method for the Student ID number. Also create a get method that returns one of the Student’s CollegeCourses; the method takes an integer argument and returns the CollegeCourse in that position (0 through 4). Next, create a set method that sets the value of one of the Student’s CollegeCourse objects; the method takes two arguments—a CollegeCourse and an integer representing the CollegeCourse’s position (0 through 4). B. Write an application that prompts a professor to enter grades for five different courses each for 10 students. Prompt the professor to enter data for one student at a time, including student ID and course data for…

1: Create a new class with attributes name and address. Both data type will be String. Create a constructor and assign the parameters to the attributes. Now override the toString() method. Is this possible? 2: Create a class with the main method and create an instance of the class that you created in Test Stem 1. What method can you call to get the hashCode of your class? 3: What is the return type of the hash code ? 4: Create an instance of the string in your test class and assign a value. Which of the following operators can be used in conjunction with a string object? + - & . += 5: Supposed that we have a string with a value “This is my string.”. Which method can be used to extract a specific word from the given string? 6: Supposed that we have a string with a value “This is my string.”. Which expression can be used to extract the word “my” from the given string? 7: Now create an String and assign a value with spaces in the beginning, end and middle. Try out the method…
Modified Circle class and test file: Add a new attribute for color (or any other new attribute) Add get/set methods for this new instance variable, including data validation in set method (assuming background is black, i.e. circle color can't be black, reset to any non-black color if black is entered ). Add a new constructor to pass the color attribute as an argument. Add an instance method to display all properties of a Circle object. Create 2 objects using different constructors in test file, with invalid data. Use this test java file test java file: class CircleTest{ public static void main(String[] args){ int num = 10; Circle c1 = new Circle(0.001); Circle c2 = new Circle("black", -9); c1.display(); c2.display(); c1.setRadius( -1); c1.setColor("black"); c1.display(); }}

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…
Add a list of procedures in your patient class, fill them and print them with the patient data. This is called composition which is a "has a" relationship. A patient has procedures. Write a class named Patient that has attributes for the following data: First name, middle name, and last name Address, city, state, and ZIP code Phone number Name and phone number of emergency contact The Patient class’s _ _init_ _ method should accept an argument for each attribute. The Patient class should also have accessor and mutator methods for each attribute. Next, write a class named Procedure that represents a medical procedure that has been performed on a patient. The Procedure class should have attributes for the following data: Name of the procedure Date of the procedure Name of the practitioner who performed the procedure Charges for the procedure The Procedure class’s _ _init_ _ method should accept an argument for each attribute. The Procedure class should also have accessor and mutator…
Please written by computer source What will the application do? Display a set of at least 6 cars (at least 3 new and 3 used) along with Add and Quit options Let the user select one of the cars. Ask if they want to buy the car. If they enter yes, remove it from the list. If they want to add another car to the list, get the details, create a new instance of the appropriate class (Car class for new cars, or UsedCar), and add it to your data collection. Keep looping until they choose to quit. Build Specifications If your instructors tells you to work in pairs, stay with your assigned pair for this lab. Create a class named Car to store the data about a car. This class should contain:Data members for car details A string for the make A string for the model An int for the year A decimal for the price A no-arguments constructor that sets data members to default values (blanks or your choice) A constructor with four arguments matching the order above Properties for all data members An…
This is the question that is confusing me - A. Create a CollegeCourse class. The class contains fields for the course ID (for example, CIS 210), credit hours (for example, 3), and a letter grade (for example, A). Include get and set methods for each field. Create a Student class containing an ID number and an array of five CollegeCourse objects. Create a get and set method for the Student ID number. Also create a get method that returns one of the Student’s CollegeCourses; the method takes an integer argument and returns the CollegeCourse in that position (0 through 4). Next, create a set method that sets the value of one of the Student’s CollegeCourse objects; the method takes two arguments—a CollegeCourse and an integer representing the CollegeCourse’s position (0 through 4).
