help creating a ULM Class Diagram, please. I have included my 3 classes of code below (UserInput, Participant, and Exchange Results). // Participant Class class Participant { // Participants private String name; private int age; public Participant(String name, int age) { this.name = name; this.age = age;
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:
