How do I print more than one enum value using arrays?-CodePudding

I'm not sure how to formulate the question but say I have a pizza with toppings, and I want (through the main class) to print or call to the description of this pizza that contains not one but two toppings, how should I do this?

My toppings class is an enum so I've tried, so far, this:

public class Pizza{

    private Toppings[] toppings;

    public Pizza(Toppings[] toppings){
        this.toppings = new Toppings[]{Toppings.tomatosauce, Toppings.cheese};
    }

    public String toString(){
        return "Toppings: "   toppings;
    }

}

then in the main class:

public class Main {

    public static void main(String[] args) {
        Pizza pizza = new Pizza(Toppings.cheese);
        System.out.println(pizza);
    }
}

Obviously, this is wrong, as it only prints the cheese topping. Any hints?

CodePudding user response：

You can use this:

public class Pizza{

    private Toppings[] toppings;

    public Pizza(Toppings ...toppings){
        this.toppings = toppings;
    }

    public String toString(){
        return "Toppings: "   Arrays.toString(toppings);
    }

}

class Main {

    public static void main(String[] args) {
        Pizza pizza = new Pizza(Toppings.cheese, Toppings.tomato);
        System.out.println(pizza);
    }
}

enum Toppings { cheese, tomato }

Pizza pizza = new Pizza(new Toppings[]{Toppings.cheese, Toppings.tomato});

instead and change the constructor of Pizza:

public Pizza(Toppings[] topping) {
    ...
}
