Java代码

好的，这是Java代码实现：

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

class Book {
    private String type;
    private String name;
    private double price;
    private String uniqueProp;

    public Book(String type, String name, double price, String uniqueProp) {
        this.type = type;
        this.name = name;
        this.price = price;
        this.uniqueProp = uniqueProp;
    }

    public String getType() {
        return type;
    }

    public String getName() {
        return name;
    }

    public double getPrice() {
        return price;
    }

    public String getUniqueProp() {
        return uniqueProp;
    }

    public String toString() {
        return "书名: " + name + ", 单价: " + price + ", 独有属性: " + uniqueProp;
    }
}

public class BookManager {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        ArrayList<Book> books = new ArrayList<>();

        // 输入书籍信息
        int n = scanner.nextInt();
        scanner.nextLine(); // 读取输入n后的换行符
        for (int i = 0; i < n; i++) {
            String type = scanner.nextLine();
            String name = scanner.nextLine();
            double price = scanner.nextDouble();
            scanner.nextLine(); // 读取输入price后的换行符
            String uniqueProp = scanner.nextLine();
            books.add(new Book(type, name, price, uniqueProp));
        }

        // 查询书籍信息
        String queryType = scanner.nextLine();
        boolean found = false;
        for (Book book : books) {
            if (book.getType().equals(queryType)) {
                System.out.println(book);
                found = true;
            }
        }
        if (!found) {
            System.out.println("Don't have this kind of book");
        }
    }
}

以上代码实现了输入n本书的信息，并支持查询指定类型的书籍信息，可根据需要进行修改和扩展。
