arraylist-我怎麼才能在main裡輸出下面的bkdata,謝謝各位大神

我怎麼才能在main裡輸出下面的bkdata,謝謝各位大神

public class BookData {
private static ArrayList book = new ArrayList();
private static ArrayList customer = new ArrayList();

public static ArrayList<Customer> getCustomer() {
    return customer;
}

public static void setCustomer(ArrayList<Customer> customer) {
    BookData.customer = customer;
}

public static ArrayList<Book> getBook() {
    return book;
}

public static void setBook(ArrayList<Book> book) {
    BookData.book = book;
}

public static void bkdata(){                            //創建書籍種類和會員信息
    BookDaoImp bookDaoImp = new BookDaoImp();
    bookDaoImp.create("計算機類", 300) ;
    bookDaoImp.create("文史類", 300);
    bookDaoImp.create("小說類", 300);
    CustomerDaoImp customerDaoImp = new CustomerDaoImp();
    customerDaoImp.create("張三","vip會員");
    customerDaoImp.create("李四","會員");
    customerDaoImp.create("王五","普通");
}

}

最佳回答：

import java.util.ArrayList;
import java.util.List;

// public static ArrayList getCustomer() {

// public static void setCustomer(ArrayList customer) {

public static void bkdata() {                            //創建書籍種類和會員信息

    BookDaoImp bookDaoImp = new BookDaoImp();
    bookDaoImp.create("計算機類", 300);
    bookdaoimp.add(bookDaoImp);
    BookDaoImp bookDaoImp1 = new BookDaoImp();
    bookDaoImp1.create("文史類", 300);
    bookdaoimp.add(bookDaoImp1);
    BookDaoImp bookDaoImp2 = new BookDaoImp();
    bookDaoImp2.create("小說類", 300);
    bookdaoimp.add(bookDaoImp2);

    //輸出.
    for (BookDaoImp bk : bookdaoimp) {

        System.out.println("name->" + bk.getName() + ",total->" + bk.getTotal());
    }

// CustomerDaoImp customerDaoImp = new CustomerDaoImp();
// customerDaoImp.create("張三","vip會員");
// customerDaoImp.create("李四","會員");
// customerDaoImp.create("王五","普通");
}

public static void main(String[] args) {
    bkdata();
}

}

class BookDaoImp {

private String name;
private int total;

public void create(String name, int total) {
    setName(name);
    setTotal(total);
}


public String getName() {
    return name;
}

public void setName(String name) {
    this.name = name;
}

public int getTotal() {
    return total;
}

public void setTotal(int total) {
    this.total = total;
}

}

你的代碼不全，大致就是這樣輸出的。
