Question

我尝试从URL地址读取文本文件并拆分＆amp;将其转换为ArrayList 我可以阅读它并将其打印到控制台但不知道我应该如何将InputStream或Stream转换为Arraylist。

这就是我现在所得到的：

My Book课程。

import java.io.*;
import java.math.BigDecimal;
import java.net.MalformedURLException;
import java.net.URL;
import java.util.stream.Stream;

public class Book implements BookList {

private String title;
private String author;
private BigDecimal price;

public static void main(String[] args) {
    try (InputStream is = new URL("http://www.contribe.se/bookstoredata/bookstoredata.txt").openConnection().getInputStream();
    BufferedReader reader = new BufferedReader(new InputStreamReader(is));
    Stream<String> stream = reader.lines()) {

        stream.forEach(System.out::println);

    } catch (MalformedURLException | FileNotFoundException e) {
        System.out.println("Could not find the file.");
        e.printStackTrace();

    } catch (IOException e) {
        System.out.println("IOException error.");
        e.printStackTrace();
    }
}

@Override
public Book[] list(String searchString) {
    return new Book[0];
}

@Override
public boolean add(Book book, int quantity) {
    return false;
}

@Override
public int[] buy(Book... books) {
    return new int[0];
}

我的界面：

public interface BookList {

public Book[] list(String searchString);
public boolean add(Book book, int quantity);
public int[] buy(Book... books);

}

将URL-address转换为String List
