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:
Question
Can you call a constructor from another 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.
Problem Statement#
A class can have multiple parameterized constructors which can call each other.
You are given a partially completed code of a Car class in the editor. Modify the parametrized constructor which assigns parameters to the required fields.
Input#
carName, carModel, carCapacity
Output#
carName, carModel, carCapacity
Sample Input#
"Ferrari", "F8", "100"
Sample Output#
"Ferrari", "F8", "100"
Part of solution
// Car class
class Car {
// Private Fields
private String carName;
private String carModel;
private String carCapacity;
// Default Constructor
public Car() {
this.carName = "";
this.carModel = "";
this.carCapacity = "";
}
// Parameterized Constructor 1
public Car(String name, String model) {
this.carName = name;
this.carModel = model;
}
// Parameterized Constructor 2
public Car(String name, String model, String capacity) {
// Write your code here
}
// Method to return car details
public String getDetails() {
return this.carName + ", " + this.carModel + ", " + this.carCapacity;
}
}
