Solution: Flexible Pizza Orders

Explore how to implement flexible pizza orders in Java by using constructor chaining to handle default values smoothly. Learn to enforce encapsulation and build descriptive outputs through string concatenation, enhancing object-oriented design skills within Java's class structure.

We'll cover the following...
Java 25
public class Pizza {
    private String size;
    private String crust;
    private String cheese;
    // Master Constructor: The only one that sets the fields
    public Pizza(String size, String crust, String cheese) {
        this.size = size;
        this.crust = crust;
        this.cheese = cheese;
    }
    // Intermediate: Supplies "Normal" cheese and delegates
    public Pizza(String size, String crust) {
        this(size, crust, "Normal");
    }
    // Basic: Supplies "Thin" crust and delegates to the Intermediate constructor
    public Pizza(String size) {
        this(size, "Thin"); 
    }
    public void printDescription() {
        // Use standard concatenation to construct the output
        System.out.println("Pizza: " + size + ", " + crust + " crust, " + cheese + " cheese.");
    }
}
