The following code is in Java: public class Vehicle // Superclass { private double cost; public Vehicle(double c) { cost = c; } (Other methods . . .) // assume these are given and they’re OK. } public class Car extends Vehicle // Subclass { private int passengers; public Car(int p) { passengers = c; } (Other methods . . .) // assume these are given and they’re OK. } 1) What problems are in the code above? 2) What is needed to fix the issue of the code?
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:
The following code is in Java:
public class Vehicle // Superclass
{
private double cost;
public Vehicle(double c)
{
cost = c;
}
(Other methods . . .) // assume these are given and they’re OK.
}
public class Car extends Vehicle // Subclass
{
private int passengers;
public Car(int p)
{
passengers = c;
}
(Other methods . . .) // assume these are given and they’re OK.
}
1) What problems are in the code above?
2) What is needed to fix the issue of the code?
