Classes and Objects in Java

Have you ever wondered how Java models real world concepts in code? The secret lies in the density of classes and objects. To make it better again, let’s review these important points with possible examples.

The Blueprint Analogy

Think of a class as an architect’s blueprint and objects as the buildings constructed from that blueprint. Just as a single blueprint can create multiple unique buildings, a Java class can instantiate multiple distinct objects.

public class Building {
    private String address;
    private int floors;
    private String purpose;
    
    // Constructor
    public Building(String address, int floors, String purpose) {
        this.address = address;
        this.floors = floors;
        this.purpose = purpose;
    }
}

// Creating multiple objects
Building office = new Building("123 Business Ave", 20, "Commercial");
Building apartment = new Building("456 Living St", 5, "Residential");

The Power of Encapsulation

Classes in Java aren’t just containers for data — they’re guardians of it. Through encapsulation, we can control how data is accessed and modified, ensuring our objects maintain their integrity.

public class BankAccount {
    private double balance;
    private String accountNumber;
    
    public void…
