Step by step
Solved in 3 steps with 3 images
- Write a Number class that holds a double, and add overloaded operators for +, –, *, /, and assignment. Choose the return values for these functions so that expressions can be chained together, and for efficiency. Write an automatic type conversion operator int( ). Please submit code inCan you implement the Derived Class Parameterized constructor? A solution is placed in the "solution" section to help you, but we would suggest you try to solve it on your own first. Implement the constructor Dell(String name) of the Derived Class Dell which takes a string, name. We have already implemented the Base Class Laptop with the member function getName() and a parameterized constructor. Input# Laptop name is being passed through the parameterized constructor. Output# getName() method is returing Laptop name. Sample Input# Dell dell = new Dell("Dell Inspiron"); Sample Output# "Dell Inspiron"Please write a Java program with at least two classes. Use a circle to represent it! The class should have at least one non-static setter method and one non-static getter. Implement at least one method test that invokes the setter method and the corresponding getter method so that the value out == the value in!
- Write an abstract class, it can be anything well defined from the very basics.Create a program that has the following classes: Point - Just like in the lecture, with attributes x and y set to 0 by default. Circle - Contains two attributes, center and radius. center is of type Point defined above (initialize a Point instance for this), while radius is set to 0 by default. The program must have the function point_in_circle(c, p) where c is a Circle and p is a Point. The function returns True if the point is within the circle, and False otherwise. You may use the math module (and nothing else) if necessary. You may also create other functions that can help you code the main function much easier. Example usage # Initialize a circle with center at (0, 0) and radius 1 (unit circle). c = Circle() c.center.x, c.center.y, c.radius = 0, 0, 1 # Initialize a point located at (1, 1) p = Point() p.x, p.y = 1, 1 # This returns False since (1, 1) is outside the circle point_in_circle(c, p)Implement the following concepts by constructing suitable classes in Java -a. Constructorsb. Constructor Overloadingc. Function Overloadingd. Function Overridinge. InheritanceCreate a class Person - Field - Name, Birthdate, Contact no and Mail idMethods - Constructor, accept and displayClass Employee - Inherits the Person classFields : Emp ID, grade, basic salary, Gross Salary, HRA (House Rent Allowance), TA (TravelingAllowance), DA (Dearness Allowance)Given:Grade Basic TAA 8000 2000B 7000 1500C 6000 1000D 5000 500Calculate Gross Salary :Gross Salary = Basic + HRA (20% of Basic) + DA (50% Basic) + TAe.g if Basic = 8000TA = 2000HRA = 20% of 8000 = 1600DA = 50 % of 8000 = 4000Gross = 8000 + 2000 + 1600 + 4000 = 15600Optional : you can implement increment function in which you can change grade of an employee andrecalculate salary with new grade
- If class A is a subclass of class B, then A has access to all of B's instance variables, including private ones. True FalseConsider the following class implementation, which represents a price in dollars and cents: class Price { private: int dollars; int cents; public: Price() { dollars = cents = 0; } Price(int d, int c) { dollars = d; cents = c; } bool operator!=(Price); bool operator<(Price); }; Write an implementation for both overloaded operators. != should return true if the Prices are not equivalent, and should return false if they are equivalent. < should return true if the Price of the calling object (left object) is less than the parameter Price object (right object). You do not need to demonstrate calling these operators.Is the following a legal definition of the member function isCrazy in the derived class SmartBut discussed in Self-Test Exercise 2? Explain your answer. (Remember, the question asks if it is legal, not if it is a sensible definition.) bool SmartBut::isCrazy( ) const { if (a > b) return false; else return true; }
- PLZ help with the following: IN JAVA Given the following code (where the function FunTest() and the main method are inside one class in the same file where classes X, Y and Z are), predict what is the output?Q2: Consider the following statements: public class YClass { private int a; private int b; public void one() { } public void two(int x, int y); { } public YClass() { } } class XClass extends YClass { private int z; public void one() { } public XClass() { } } YClass yObject; XClass xObject; Write the definition of the default constructor of YClass so that the instance variables of YClass are initialized to 0. Write the definition of the default constructor of XClass so that the instance variables of XClass are initialized to 0.
