如何修改我的脚本以将每一行添加到 ArrayList

Question

这是我的代码，我需要将我的 file.txt 的每一行添加到一个 ArrayList 中，稍后我将通过使用本体（本体已在脚本中加载）进行注释，因此当我尝试简单的短语时它可以工作，例如：

//ar.add("军事攻击");

但是当我想使用文件中的行时，我正在伤害一堵墙？请你 指导我

Answer 1

如果您只需要将文本文件加载到您的 ArrayList 对象中，那么您几乎已经完成了，只需将 ArrayList ar 定义移动到您的 try/catch 块之前，然后在您的 while 循环中添加该行阅读它。

还将br.close 移动到finally 块

ArrayList<String> ar = new ArrayList<String>();

try {
    br = new BufferedReader(new FileReader(new File("D:/ekelodjo/OntoTest/CorpusTexte.txt")));
    while ((line = br.readLine()) != null) {
        ar.add(line);
    }
} catch (FileNotFoundException e) {
} catch (IOException e) {
} finally {
    try {
        br.close();
    } catch (IOException e) {
    }
}

Answer 2

你可以试试这个

    ArrayList<String> ar = new ArrayList<String>();

    try {
        br = new BufferedReader(new FileReader(new File(
                "D:/ekelodjo/OntoTest/CorpusTexte.txt")));
        while ((line = br.readLine()) != null) {
            // line = br.readLine();
            System.out.println("line :" + line);
            ar.add(line);
        }
        br.close();
    } catch (FileNotFoundException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }
