Java calling method in another class

Question

I am trying to create a Java class with certain number of pizzas that decreases in number

if someone steals it.

I have two classes.

class House where pizza is,

public class House { private static int totalPizzas; public House() { totalPizzas = totalPizzas; } public int getTotalPizzas() { return totalPizzas; } public static void setTotalPizzas(int totalPizzas) { totalPizzas = totalPizzas - Thief.stealPizza(House stolenPizza); } }

and class Thief that steals the pizza.

public class Thief { private String name; private int age; public Thief() { name = "abc"; age = 11; } public static void stealPizza(House stolenPizza) { ??????? } }

My main concern is the ??????? part where I feel like I should set stolenPizza to certain

integers but

stolenPizza = 1;

certainly does not work.

Could someone give me a bit of advice on how I should approach this?

Thank you very much for reading.

Make a main class that have object of both class. You probably don't need any static methods besides main — Yoshikage Kira

Thief.stealPizza(House stolenPizza) is not valid syntax for a method call. And you can't call a method that returns void as part of an arithmetic expression — UnholySheep

One way to do it would be to do something like:

 public class Thief { private String name; private int age; public Thief() { name = "abc"; age = 11; } public static void stealPizza() { House.setTotalPizzas(House.totalPizzas - 1); } } public class House { private static int totalPizzas; public House() { totalPizzas = totalPizzas; } public int getTotalPizzas() { return totalPizzas; } public static void setTotalPizzas(int totalPizzas) { House.totalPizzas = totalPizzas; } }

Though static methods make no sense.

I can see the value. There is no relation between the house and the thief. What if a Thief wants to steal jewels? What they donate pizza? A better option might be to create a singleton to manage the pizza count, but again, this is just one way to do it. Also, without more context who is to say it isn't the right option; let alone suggest a new way.

For thief maybe (Assuming there is only one thief) but not for House. A thief can steal pizzas from multiple homes

Do you know there are multiple homes? Maybe it's a "Pizza house" restaurant.

Fair enough but shouldn't getter be static as well?

Your constructor is missing something if I understand your code right:

Your code

 public House() { totalPizzas = totalPizzas; }

will set the amount of totalPizzas on itself without assigning any "real" integer value to it. Try

 public House(int totalPizzas) { totalPizzas = totalPizzas; }

so that you actually can assign a number of Pizzas to the house when calling the constructor, for example:

House house = new House (12);

if you want to have 12 Pizzas in the house.
