帮我用java代码写一个笔记本管理系统

好的，我可以帮你设计一个简单的笔记本管理系统。首先，你需要定义数据模型来存储笔记本信息，例如品牌、型号、颜色和价格等。然后，你可以使用Java编写控制台应用或者图形用户界面 (GUI) 应用来实现该系统。以下是一个简单的控制台应用的代码示例：

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

public class NotebookManager {
    private ArrayList<Notebook> notebookList;

    public NotebookManager() {
        this.notebookList = new ArrayList<Notebook>();
    }

    public void addNotebook(Notebook notebook) {
        this.notebookList.add(notebook);
    }

    public void removeNotebook(Notebook notebook) {
        this.notebookList.remove(notebook);
    }

    public void displayNotebookList() {
        System.out.println("Notebook List:");
        for (Notebook notebook : this.notebookList) {
            System.out.println(notebook);
        }
    }

    public static void main(String[] args) {
        NotebookManager notebookManager = new NotebookManager();
        Scanner scanner = new Scanner(System.in);
        int choice = 0;

        do {
            System.out.println("Notebook Management System");
            System.out.println("===========================");
            System.out.println("1. Add a new notebook");
            System.out.println("2. Remove an existing notebook");
            System.out.println("3. Display notebook list");
            System.out.println("4. Exit");
            System.out.println("Enter your choice:");

            choice = scanner.nextInt();

            switch (choice) {
                case 1:
                    System.out.println("Add a new notebook");
                    System.out.println("===================");
                    System.out.println("Enter brand name:");
                    String brand = scanner.next();
                    System.out.println("Enter model:");
                    String model = scanner.next();
                    System.out.println("Enter color:");
                    String color = scanner.next();
                    System.out.println("Enter price:");
                    double price = scanner.nextDouble();
                    Notebook newNotebook = new Notebook(brand, model, color, price);
                    notebookManager.addNotebook(newNotebook);
                    break;
                case 2:
                    System.out.println("Remove an existing notebook");
                    System.out.println("=============================");
                    notebookManager.displayNotebookList();
                    System.out.println("Enter index to remove:");
                    int index = scanner.nextInt();
                    Notebook notebook = notebookManager.notebookList.get(index);
                    notebookManager.removeNotebook(notebook);
                    break;
                case 3:
                    System.out.println("Display notebook list");
                    System.out.println("=======================");
                    notebookManager.displayNotebookList();
                    break;
                case 4:
                    System.out.println("Goodbye!");
                    break;
                default:
                    System.out.println("Invalid choice!");
            }
        } while (choice != 4);
    }
}

class Notebook {
    private String brand;
    private String model;
    private String color;
    private double price;

    public Notebook(String brand, String model, String color, double price) {
        this.brand = brand;
        this.model = model;
        this.color = color;
        this.price = price;
    }

    public String getBrand() {
        return brand;
    }

    public String getModel() {
        return model;
    }

    public String getColor() {
        return color;
    }

    public double getPrice() {
        return price;
    }

    @Override
    public String toString() {
        return String.format("Brand: %s, Model: %s, Color: %s, Price: %.2f", brand, model, color, price);
    }
}

这个笔记本管理系统可以执行以下操作：

1. 添加一个新的笔记本
2. 删除一个已有的笔记本
3. 显示当前的笔记本列表
4. 退出系统

你可以选择用一个简单的菜单界面命令来执行这些操作。
