将文本文件读入数组列表

问题描述

我对 Java 真的很陌生，所以我在弄清楚这一点时遇到了一些麻烦.所以基本上我有一个看起来像这样的文本文件:

I really new to Java so I'm having some trouble figuring this out. So basically I have a text file that looks like this:

1:John:false
2:Bob:false
3:Audrey:false

如何从文本文件中为每一行创建一个 ArrayList?

How can I create an ArrayList from the text file for each line?

推荐答案

从文件中读取并将每一行添加到 arrayList 中.例如，请参阅代码.

Read from a file and add each line into arrayList. See the code for example.

public static void main(String[] args) {

        ArrayList<String> arr = new ArrayList<String>();
        try (BufferedReader br = new BufferedReader(new FileReader(<your_file_path>)))
        {

            String sCurrentLine;

            while ((sCurrentLine = br.readLine()) != null) {
                arr.add(sCurrentLine);
            }

        } catch (IOException e) {
            e.printStackTrace();
        }

    }
