Java读取在其列文件中具有不同数字的txt，并将数据存储在数组列表中

File file = new File("file.txt");
FileReader fileReader = new FileReader(file);
BufferedReader bufferedReader = new BufferedReader(fileReader);

ArrayList<Integer> dataList = new ArrayList<>();

String line;
while ((line = bufferedReader.readLine()) != null) {
    int number = Integer.parseInt(line);
    dataList.add(number);
}

bufferedReader.close();
