设计一个java图书实体类，在BookType中声明属性BookTypeID，BookTypeName，TypeDES，还有相应的方法

好的，以下是一个简单的Java图书实体类设计，其中包含了BookType类的属性和方法声明：

public class Book {
    private int bookID;
    private String bookName;
    private String author;
    private String publisher;
    private double price;

    public Book(int bookID, String bookName, String author, String publisher, double price) {
        this.bookID = bookID;
        this.bookName = bookName;
        this.author = author;
        this.publisher = publisher;
        this.price = price;
    }

    public int getBookID() {
        return bookID;
    }

    public void setBookID(int bookID) {
        this.bookID = bookID;
    }

    public String getBookName() {
        return bookName;
    }

    public void setBookName(String bookName) {
        this.bookName = bookName;
    }

    public String getAuthor() {
        return author;
    }

    public void setAuthor(String author) {
        this.author = author;
    }

    public String getPublisher() {
        return publisher;
    }

    public void setPublisher(String publisher) {
        this.publisher = publisher;
    }

    public double getPrice() {
        return price;
    }

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

public class BookType {
    private int bookTypeID;
    private String bookTypeName;
    private String typeDES;

    public BookType(int bookTypeID, String bookTypeName, String typeDES) {
        this.bookTypeID = bookTypeID;
        this.bookTypeName = bookTypeName;
        this.typeDES = typeDES;
    }

    public int getBookTypeID() {
        return bookTypeID;
    }

    public void setBookTypeID(int bookTypeID) {
        this.bookTypeID = bookTypeID;
    }

    public String getBookTypeName() {
        return bookTypeName;
    }

    public void setBookTypeName(String bookTypeName) {
        this.bookTypeName = bookTypeName;
    }

    public String getTypeDES() {
        return typeDES;
    }

    public void setTypeDES(String typeDES) {
        this.typeDES = typeDES;
    }
}

以上代码中，BookType类中包含了bookTypeID，bookTypeName和typeDES三个属性，并且为每个属性都提供了getter和setter方法，以便在其他地方对其进行访问和修改。
