如何用Java制作简单的客户反馈系统

public class Feedback {
    private String name;
    private String email;
    private int rating; // 1-5分
    private String comment;
public Feedback(String name, String email, int rating, String comment) {
    this.name = name;
    this.email = email;
    this.rating = rating;
    this.comment = comment;
}

// Getter方法便于后续显示
public String getName() { return name; }
public String getEmail() { return email; }
public int getRating() { return rating; }
public String getComment() { return comment; }

@Override
public String toString() {
    return "姓名：" + name + " | 邮箱：" + email +
           " | 评分：" + rating + "星 | 评论：" + comment;
}
}

Scanner scanner = new Scanner(System.in);
List feedbacks = new ArrayList<>();
while (true) {
System.out.println("\n--- 客户反馈系统 ---");
System.out.println("1. 提交反馈");
System.out.println("2. 查看所有反馈");
System.out.println("3. 退出");
System.out.print("请选择操作：");
int choice = scanner.nextInt();
scanner.nextLine(); // 消费换行符

if (choice == 1) {
    System.out.print("姓名："); String name = scanner.nextLine();
    System.out.print("邮箱："); String email = scanner.nextLine();
    System.out.print("评分（1-5）："); int rating = scanner.nextInt();
    scanner.nextLine(); // 清除缓冲
    System.out.print("评论："); String comment = scanner.nextLine();

    feedbacks.add(new Feedback(name, email, rating, comment));
    System.out.println("感谢您的反馈！");
} else if (choice == 2) {
    System.out.println("\n当前所有反馈：");
    for (Feedback f : feedbacks) {
        System.out.println(f);
    }
} else if (choice == 3) {
    System.out.println("再见！");
    break;
} else {
    System.out.println("无效选择，请重试。");
}
}
