Solution: Flexible Pizza Orders

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.");
    }
