Implement constructors for each of the three subclasses. Each constructor should call the superclass constructor to set the name. Here is one example: public IDCard(String n, String id) { super(n); idNumber = id; }
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:
Lab 8.2 Provide constructors for Card subclasses
Implement constructors for each of the three subclasses. Each constructor should call the superclass constructor to set the name. Here is one example:
public IDCard(String n, String id)
{
super(n);
idNumber = id;
}
three sub class of the main class and constructor of each subclass is call on the super class
