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.

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
{

(Other methods . . .) // assume these are given and they’re OK.
}
// Subclass
public class Car extends Vehicle
{
public Car(double c)
{
cost = c;
}
}
