Create a class of subtraction having two private data members. Create class
methods to get data from users and for subtraction of data members.
appropriate access modifiers for class methods.
Step by step
Solved in 2 steps with 1 images
- Create a class Student with attributes StudentName, Enrollment, semester, section, course MarksObtained and Grade. Write appropriate constructors, get and set functions for data members. The data member grade is automatically calculated based on marks obtained out of 100 for each course.Class field corruption must be prevented.You need a method of protecting class fields against unintended corruption.
- In Java programming What is the difference between a static data member and an instance data member? Declare a unique class (i.e., different from a classmate's posting) that contains an instance data member and a static data member (in the same class). Explain how each of the members is used in the class.Write a class called Person that has two private data members - the person's name and age. It should have an init method that takes two values and uses them to initialize the data members. It should have a get_age method. Does the code have a get_age method?Question 5: 1. Explain how the Dealer class can maintain record of multiple cars using minimal code. 2. Write an addCar() method that receives a Car object and adds it to the Dealer class. 3. Write a contains method that takes the name of a Car and determines whether the Dealer has that Car in its collection. 4. Write part of the code that removes the car from the dealer class that is sold.
- Create a class of any domain i.e. university, showroom, student, shop. Also mention attributes for them and initialize the values using constructor and show the values for each object using custom function (out side the class) hint: min no of objects 2Question 5:1. Explain how the Dealer class can maintain record of multiple cars using minimal code.2. Write an addCar() method that receives a Car object and adds it to the Dealer class.3. Write a contains method that takes the name of a Car and determines whether the Dealerhas that Car in its collection.4. Write part of the code that removes the car from the dealer class that is sold.Challenge exercise The following object creation will result in the constructor of the Date class being called. Can you write the constructor’s header? new Date("March", 23, 1861) Try to give meaningful names to the parameters
- Overloading is when you create another way for the operation to be used like with different data types whereas overriding is like using Inheritance and having the child class have it’s own method. answer choices True FalseModified 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(); }}You need a strategy to protect class fields from being accidentally corrupted in any manner.
