java从键盘依次输入6本图书信息(以顺序表存放),分别编写按书号、书名及价格等信息的查找方法,实现图书信息的查找。的main方法

好的，以下是Java代码实现：

import java.util.Scanner;

public class Book {
    private String bookNo;
    private String bookName;
    private double price;

    public Book(String bookNo, String bookName, double price) {
        this.bookNo = bookNo;
        this.bookName = bookName;
        this.price = price;
    }

    public String getBookNo() {
        return bookNo;
    }

    public String getBookName() {
        return bookName;
    }

    public double getPrice() {
        return price;
    }

    public static int searchByBookNo(Book[] books, String bookNo) {
        for (int i = 0; i < books.length; i++) {
            if (books[i].getBookNo().equals(bookNo)) {
                return i;
            }
        }
        return -1;
    }

    public static int searchByBookName(Book[] books, String bookName) {
        for (int i = 0; i < books.length; i++) {
            if (books[i].getBookName().equals(bookName)) {
                return i;
            }
        }
        return -1;
    }

    public static int searchByPrice(Book[] books, double price) {
        for (int i = 0; i < books.length; i++) {
            if (books[i].getPrice() == price) {
                return i;
            }
        }
        return -1;
    }

    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        Book[] books = new Book[6];
        for (int i = 0; i < books.length; i++) {
            System.out.println("请输入第" + (i + 1) + "本书的书号、书名和价格：");
            String bookNo = scanner.next();
            String bookName = scanner.next();
            double price = scanner.nextDouble();
            books[i] = new Book(bookNo, bookName, price);
        }
        System.out.println("请输入查找方式(1.按书号查找 2.按书名查找 3.按价格查找)：");
        int searchType = scanner.nextInt();
        switch (searchType) {
            case 1:
                System.out.println("请输入要查找的书号：");
                String bookNo = scanner.next();
                int indexByBookNo = searchByBookNo(books, bookNo);
                if (indexByBookNo != -1) {
                    System.out.println("找到了该书，序号为：" + (indexByBookNo + 1));
                } else {
                    System.out.println("未找到该书！");
                }
                break;
            case 2:
                System.out.println("请输入要查找的书名：");
                String bookName = scanner.next();
                int indexByBookName = searchByBookName(books, bookName);
                if (indexByBookName != -1) {
                    System.out.println("找到了该书，序号为：" + (indexByBookName + 1));
                } else {
                    System.out.println("未找到该书！");
                }
                break;
            case 3:
                System.out.println("请输入要查找的价格：");
                double price = scanner.nextDouble();
                int indexByPrice = searchByPrice(books, price);
                if (indexByPrice != -1) {
                    System.out.println("找到了该书，序号为：" + (indexByPrice + 1));
                } else {
                    System.out.println("未找到该书！");
                }
                break;
            default:
                System.out.println("输入有误！");
                break;
        }
    }
}

这个程序实现了从键盘输入6本图书信息，并提供了三种查找方式：按书号、书名和价格进行查找。
