Java在列表末尾添加

Question

我有一个读书类。我想在列表末尾添加一个元素

public class Book {
private String title;
private String authorName;
private double price;


/**
 * @param title
 * @param authorName
 * @param price
 */
public Book(String title, String authorName, double price) {
    setTitle(title);
    setAuthorName(authorName);
    setPrice(price);
}

public String getTitle() {
    return title;
}

public void setTitle(String title) {
    this.title = title;
}

public String getAuthorName() {
    return authorName;
}

public void setAuthorName(String authorName) {
    this.authorName = authorName;
}

public double getPrice() {
    return price;
}

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

还有一个 Booklist 类，它有一个方法 append 可以将书籍添加到列表中，但我无法弄清楚如何将值输入到列表中

public class BookList {

/**
 * books will be stored in an array of strings
 */

private Book[] books;
// *** TODO *** you will need to add more private members variables

public BookList(int N) {
    // TODO Auto-generated method stub  
}



public void append(Book book) throws BookListFull {
    // TODO Auto-generated method stub 
}

我想在列表末尾添加元素请帮助我如何做谢谢

Answer 1

public class BookList {
  List<Book> bookList= new ArrayList<Book>();

  ...

  public void append(Book book) throws BookListFull {
    bookList.add(book); 
  }
}
