Question

I am expanding my pizza class, I need some help with this!! Here is my original code, please help me off of this!!

package pizza;
import java.util.HashSet;
import java.util.Set;

public class Pizza {

// Declare enums
public enum Size{
SMALL,
MEDIUM,
LARGE,
JUMBO
}
  
public enum Crust{
CHEESY,
HAND_TOSSEDS,
THIN_AND_CRISPY,
DEEP_PAN
}

public enum Toppings{
PEPPERONI,
CHEESE,
ANCHOVIES,
SAUSAGE,
PINEAPPLE,
HAM,
PEPPERS
}
  
// declare variables
private Size pizzaSize;
private Crust crustType;
private Set pizzaToppings = new HashSet();
  
public Pizza(){
  
}
  
public Pizza(Size pizzaSize, Crust crustType) {
this.pizzaSize = pizzaSize;
this.crustType = crustType;
}

public Size getPizzaSize() {
return pizzaSize;
}
public void setPizzaSize(Size pizzaSize) {
this.pizzaSize = pizzaSize;
}
public Crust getCrustType() {
return crustType;
}
public void setCrustType(Crust crustType) {
this.crustType = crustType;
}

public void addTopping(Toppings topping){
this.pizzaToppings.add(topping);
}

public Set getToppings(){
return pizzaToppings;
}

public void removeTopping(Toppings topping){
this.pizzaToppings.remove(topping);
}
public String toString(){
return "A "+pizzaSize+" Pizza with "+crustType+" crust and" + " toppings: " + pizzaToppings ;
}
}

package pizza;
import pizza.Pizza.Crust;
import pizza.Pizza.Size;
import pizza.Pizza.Toppings;

public class PizzaTest {

public static void main(String[] args) {

// use constructor 1
Pizza vegieCrunch = new Pizza();
vegieCrunch.setCrustType(Crust.THIN_AND_CRISPY);
vegieCrunch.setPizzaSize(Size.MEDIUM);
  
// constructor 2
Pizza doubleCheese = new Pizza(Size.LARGE, Crust.CHEESY);
  
Pizza PartyPizza = new Pizza(Size.JUMBO, Crust.DEEP_PAN);
PartyPizza.addTopping(Toppings.PEPPERONI);
PartyPizza.addTopping(Toppings.HAM);
  
// use of getters
System.out.println("Pizza Vegie Crunch:");
System.out.println("Size: "+vegieCrunch.getPizzaSize());
System.out.println("Crust Type: "+vegieCrunch.getCrustType());
  
// use of toString
System.out.println(" Pizza Double Cheese:");
System.out.println(doubleCheese.toString());
  
System.out.println(" Pizza Party Pizza:");
System.out.println(PartyPizza.toString());
  
}

}

Explanation / Answer

Please see below for the changes: The two maps can be placed in Pizza.java and can change according to you.

The required methods:

public Pizza(Size pizzaSize, Crust crustType, String speciality) {
this.pizzaSize = pizzaSize;
this.crustType = crustType;
this.speciality = speciality;
}

public Set<Toppings> getToppingsFromSpeciality(String speciality) {
return order.get(speciality);
}

public String getSpecialityFromToppings(Set<Toppings> toppings) {
return order1.get(toppings);
}

public String getSpeciality() {
return speciality;
}

public void setSpeciality(String speciality) {
this.speciality = speciality;
}

Changes to toString Method:

@Override
public String toString() {

if (pizzaToppings.size() == 0) {
return "A " + pizzaSize + " Pizza with " + crustType + " crust";
}
String sp = getSpecialityFromToppings(pizzaToppings);
if (sp != null) {
return "A " + pizzaSize + " Pizza with " + crustType + " crust and" + " toppings: " + pizzaToppings
+ ". Speciality = " + sp;
}
return "A " + pizzaSize + " Pizza with " + crustType + " crust and" + " toppings: " + pizzaToppings;
}

Changes to TEST Class Method:

public static void main(String[] args) {

// use constructor 1
Pizza vegieCrunch = new Pizza();
vegieCrunch.setCrustType(Crust.THIN_AND_CRISPY);
vegieCrunch.setPizzaSize(Size.MEDIUM);

// constructor 2
Pizza doubleCheese = new Pizza(Size.LARGE, Crust.CHEESY);

// constructor 3
Pizza vegCheese = new Pizza(Size.LARGE, Crust.CHEESY, "Vegetarian");

Pizza PartyPizza = new Pizza(Size.JUMBO, Crust.DEEP_PAN);
PartyPizza.addTopping(Toppings.PEPPERONI);
PartyPizza.addTopping(Toppings.HAM);

// use of getters
System.out.println("Pizza Vegie Crunch-");
System.out.println("Size: " + vegieCrunch.getPizzaSize());
System.out.println("Crust Type: " + vegieCrunch.getCrustType());

// use of getters
System.out.println("Pizza Veg Cheese-");
System.out.println("Size: " + vegCheese.getPizzaSize());
System.out.println("Crust Type: " + vegCheese.getCrustType());
System.out.println("Speciality: " + vegCheese.getSpeciality());
Set<Toppings> toppings = vegCheese.getToppingsFromSpeciality(vegCheese.getSpeciality());
System.out.print("Toppings with Speciality are: ");
for (Toppings s : toppings) {
System.out.print(s + " ");
}
System.out.println();
// use of toString
System.out.println(" Pizza Double Cheese:");
System.out.println(doubleCheese.toString());

System.out.println(" Pizza Party Pizza:");
System.out.println(PartyPizza.toString());

System.out.println(" Veg Pizza:");
System.out.println(vegCheese.toString());

}

private static final Map<String, Set<Toppings>> order = new HashMap<String, Set<Toppings>>() {
{
put("Meatlovers", new HashSet(Arrays.asList(Toppings.SAUSAGE, Toppings.CHEESE)));
put("Vegetarian", new HashSet(Arrays.asList(Toppings.PEPPERONI, Toppings.CHEESE)));
put("Hawaiian", new HashSet(Arrays.asList(Toppings.PEPPERONI, Toppings.HAM)));
put("Supreme", new HashSet(Arrays.asList(Toppings.PINEAPPLE, Toppings.CHEESE)));
}
};
private static final Map<Set<Toppings>, String> order1 = new HashMap<Set<Toppings>, String>() {
{
put(new HashSet(Arrays.asList(Toppings.SAUSAGE, Toppings.CHEESE)), "Meatlovers");
put(new HashSet(Arrays.asList(Toppings.PEPPERONI, Toppings.CHEESE)), "Vegetarian");
put(new HashSet(Arrays.asList(Toppings.PEPPERONI, Toppings.HAM)), "Hawaiian");
put(new HashSet(Arrays.asList(Toppings.PINEAPPLE, Toppings.CHEESE)), "Supreme");
}
};
