Properties – first-class citizens

Each class contains different attributes. The Person class, for example, contains the name, age, and height attributes. When a Person class is declared in Java or another programming language, these attributes are called fields of the class. When these fields are accessed by their corresponding getter and setter methods, they are called properties. To understand this concept in detail, create a Person class in Java, as follows:

public class Person {

    String name;
    int age;
    double height;

    Person(String n, int a, double h){
        name = n;
        age = a;
        height = h;
    }

    public double getHeight() {
        return height;
    }

    public void setHeight(double height) {
        this.height = height;
    }

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }

    public...
