OOPs
In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.
Constructor
The easiest way to think of a constructor in object-oriented programming (OOP) languages is:

- Can 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"Can a class have more than one constructor? If yes, justify your answer with help of a program that reads firstName and secondName then concatenates into Name. (use suitable type of constructor). C++Write down code that can declare a class of an employee with the properties, name and salary, and the methods, getSalary and getName, that return the salary and name of the employee respectively. Function members should be declared as prototypes only andinclude a parameterised constructor prototype to initialise with the name and salary.
- Make class Student, you need to add the normal constructor with parameters not default JAVAExperiment with two classes that have a straightforward derivation relationship. Insert println statements into the constructors of both the parent and child classes. In the child, do not explicitly call the function Object() { [native code] } of the parent. So, what happens? Why? Change the child's function Object() { [native code] } to explicitly call the parent's function Object() { [native code] }. What happens next?Write a class definition that creates a class called leverage with one private data member, crowbar, of type int and one public function whose declaration is void pry(). Opp Java
- I need help in this question of true or False on the concepts of OOP URGENT. True or False a)Composition is a specific type of Inheritance. b)Composition is commonly known as the "is a" relationship, where one class is a specific type of another class. c)With Association, it is common to see one class being passed into another class' parameters. In this sense, the receiving class "uses" the passed class.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( ).

- Q> Can we inherit Constructors or not?Hi can you assist me on the problem below for a class and a test class that conforms to the following specifications: 1. The name of the class is RightTriangle 2. The class has member variables base and height 3. The class has a constructor that initializes base and height 4. The class has accessors and mutators for base and height 5. The class has a toString method that produces String representation of a RightTriangle like the following example for a triangle with base 12 and height 10. Base : 12 Height 10 6. The class has a method called findArea to compute the area of the right triangle. Here is a suggested implementation. public double findArea() { return 0.5* this.base*this.height; } 7. The class using proper naming conventions Write a test class called RightTriangleTest that conforms to the following: 1. Create an object with base = 10 and height = 20, for example myTriangle. 2. To print the toString for myTriangle. 3. To print the area of myTriangle. System.out.println(“The…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.
