用java实现购物车添加购物功能

当然可以！下面是一个简单的示例代码，用Java实现购物车的添加商品功能：

import java.util.ArrayList;
import java.util.List;
import java.util.Scanner;

class Product {
    private String name;
    private double price;

    public Product(String name, double price) {
        this.name = name;
        this.price = price;
    }

    public String getName() {
        return name;
    }

    public double getPrice() {
        return price;
    }
}

class ShoppingCart {
    private List<Product> products;

    public ShoppingCart() {
        products = new ArrayList<>();
    }

    public void addProduct(Product product) {
        products.add(product);
    }

    public void displayCart() {
        System.out.println("Shopping Cart:");
        for (Product product : products) {
            System.out.println(product.getName() + " - $" + product.getPrice());
        }
    }
}

public class Main {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        ShoppingCart shoppingCart = new ShoppingCart();

        boolean shopping = true;
        while (shopping) {
            System.out.println("Enter product name (or 'exit' to finish shopping):");
            String productName = scanner.nextLine();
            if (productName.equals("exit")) {
                shopping = false;
                break;
            }

            System.out.println("Enter product price:");
            double productPrice = scanner.nextDouble();
            scanner.nextLine(); // Consume the remaining newline character

            Product product = new Product(productName, productPrice);
            shoppingCart.addProduct(product);
        }

        shoppingCart.displayCart();
    }
}

这段代码实现了一个简单的购物车程序。用户可以逐个输入商品名称和价格，程序将商品添加到购物车中。当用户输入"exit"时，程序结束，并展示购物车中的商品列表及其价格。
