根据下面描述用Java来编写程序，程序包括披萨类，培根披萨类，水果披萨类，披萨工厂类，测试类。请选择您想制作的披萨:1培根2水果水果 请输入水果的配料: :芒果，草莓，榴莲芒果，草莓请输入披萨大小: 00 请输入披萨价格: 100 披萨名称:水果披萨披萨价格:8 披萨大小:100 水果配料: 芒果，草莓 请选择您想制作的披萨:1培根2水果培根请输入培根的克数: 20 请输入披萨大小: 10 请输入披萨价格: 150 披萨名称:培根披萨披萨价格: 150 披萨大小:10 培根克数:20

披萨类:

public abstract class Pizza {
    protected String name;
    protected int size;
    protected double price;

    public String getName() {
        return name;
    }

    public int getSize() {
        return size;
    }

    public double getPrice() {
        return price;
    }

    public abstract void prepare();
}

培根披萨类:

public class BaconPizza extends Pizza {
    private int baconWeight;

    public BaconPizza(int size, double price, int baconWeight) {
        this.name = "Bacon Pizza";
        this.size = size;
        this.price = price;
        this.baconWeight = baconWeight;
    }

    public int getBaconWeight() {
        return baconWeight;
    }

    @Override
    public void prepare() {
        System.out.println("Preparing " + name + " with " + baconWeight + "g bacon, size " + size + ", and price $" + price);
    }
}

水果披萨类:

import java.util.List;

public class FruitPizza extends Pizza {
    private List<String> fruits;

    public FruitPizza(int size, double price, List<String> fruits) {
        this.name = "Fruit Pizza";
        this.size = size;
        this.price = price;
        this.fruits = fruits;
    }

    public List<String> getFruits() {
        return fruits;
    }

    @Override
    public void prepare() {
        System.out.println("Preparing " + name + " with " + fruits + ", size " + size + ", and price $" + price);
    }
}

披萨工厂类:

import java.util.Arrays;
import java.util.List;
import java.util.Scanner;

public class PizzaFactory {
    private static final Scanner scanner = new Scanner(System.in);

    public static Pizza createPizza() {
        System.out.println("请选择您想制作的披萨: 1.培根披萨 2.水果披萨");
        int choice = scanner.nextInt();

        switch (choice) {
            case 1:
                System.out.println("请输入培根的克数:");
                int baconWeight = scanner.nextInt();
                System.out.println("请输入披萨大小:");
                int size1 = scanner.nextInt();
                System.out.println("请输入披萨价格:");
                double price1 = scanner.nextDouble();
                return new BaconPizza(size1, price1, baconWeight);
            case 2:
                System.out.println("请输入水果的配料，以英文逗号分隔:");
                scanner.nextLine();
                String fruitsStr = scanner.nextLine();
                List<String> fruits = Arrays.asList(fruitsStr.split(","));
                System.out.println("请输入披萨大小:");
                int size2 = scanner.nextInt();
                System.out.println("请输入披萨价格:");
                double price2 = scanner.nextDouble();
                return new FruitPizza(size2, price2, fruits);
            default:
                throw new IllegalArgumentException("Invalid pizza choice");
        }
    }
}

测试类:

public class PizzaTest {
    public static void main(String[] args) {
        Pizza pizza = PizzaFactory.createPizza();
        pizza.prepare();
        System.out.println("披萨名称: " + pizza.getName());
        System.out.println("披萨价格: $" + pizza.getPrice());
        System.out.println("披萨大小: " + pizza.getSize());
        if (pizza instanceof BaconPizza) {
            System.out.println("培根克数: " + ((BaconPizza) pizza).getBaconWeight());
        } else {
            System.out.println("水果配料: " + ((FruitPizza) pizza).getFruits());
        }
    }
}

运行结果示例:
