            totalPayment += bill[i].getPrice();

        System.out.println("Total Payment: " + totalPayment);
    }
}

参考GPT：以下是Java的实现，符合题目要求：

import java.util.Scanner;

class Item {
    private String name;
    private double price;
    private String code;

    public Item(String name, String code) {
        this.name = name;
        this.code = code;
        this.price = 0.0;
    }

    public String getName() {
        return name;
    }

    public double getPrice() {
        return price;
    }

    public void setPrice(double price) {
        this.price = price;
    }

    public String getCode() {
        return code;
    }

    public void display() {
        System.out.println("Name: " + name + "; code: " + code + "; Price: " + price + ":");
    }
}

public class Main {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        Item[] bill = new Item[5];

        for (int i = 0; i < bill.length; i++) {
            System.out.print("Enter item " + (i+1) + " (name, price, code): ");
            String name = scanner.next();
            double price = scanner.nextDouble();
            String code = scanner.next();
            bill[i] = new Item(name, code);
            bill[i].setPrice(price);
        }

        double totalPayment = 0.0;
        for (int i = 0; i < bill.length; i++) {
            System.out.println("Item " + (i+1));
            bill[i].display();
            totalPayment += bill[i].getPrice();
        }

        System.out.println("Total Payment: " + totalPayment);
    }
}

在命令行或控制台上运行该程序，就可以输入5个条目的名称、价格和代码。然后，程序会将它们添加到一个名为bill的Item数组中，并使用setPrice方法将价格设置为输入的价格。接下来，程序会打印出每个条目的详细信息，并计算总金额。最后，程序将打印出总金额。

            String name = scanner.next();
            double price = scanner.nextDouble();
            String code = scanner.next();

            bill[i] = new Item(name, code);
