在另一个类中的一个类中使用java构造参数

我在.Author中有这个结构

package author;

public class Author {
    private String name;
    private String email;
    private char gender;

    public Author (String name, String email, char gender) {
        this.name = name;
        this.email = email;
        this.gender = gender;
    }
    public String getName () {
        return name;
    }
    public char gender () {
        return gender;
    }
    public String getEmail () {
        return email;
    }
    public void SetEmail (String userEmail) {
        email = userEmail; 
    }
    public String toString () {
        return "Author info: " + " [name: " +name + ", " + " gender: " + gender +", " + " email " + email + "]";
    }

}

我有另一个名为.Book的类，我想在.Book中的另一个构造中使用Author构造中的“name”变量，如下所示：

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

    public Book (String bookName, Author name, double price) {
        this.bookName = bookName;
        // here I'm getting an error saying ";" required
        this.author = Author name;
        this.price = price;
    }

}

我得到了一个错误（显示在第二个代码中），所以很明显我做得不对，也不知道如何做。有什么帮助吗

public class Book {
    private String bookName;
    private Author author; //it should be Author, not String
    private double price;
    private int qty;

    public Book (String bookName, Author name, double price) {
        this.bookName = bookName;
        this.author = name; //here was ur mistake
        this.price = price;
    }

}

试试这个代码。假设，在构建本书时，您确实喜欢

Book book = new Book("name", new Author("name", "name@mail", m), 22.0);

试试这个代码。假设，在构建本书时，您确实喜欢

Book book = new Book("name", new Author("name", "name@mail", m), 22.0);
