Modern Java: From Fundamentals to Advanced Architecture

Solution: Digital Product Catalog

Explore how to implement encapsulation in Java by defining classes with private fields and public methods that control data access. Understand the use of constructors, method parameters, and object instantiation to safely manage and display object data, ensuring data protection while enabling interaction.

We'll cover the following...
Java 25
public class Main {
    public static void main(String[] args) {
        // Create an instance of Product
        Product item = new Product();
        // Correctly use the public setter method to assign data
        item.setDetails("Laptop", 499.99);
        
        // Use the public method to view the data
        item.displayInfo();
    }
}
