我认为您正在尝试这样做：public static void main(String[] args) throws FileNotFoundException {&nbsp; &nbsp; Scanner in = new Scanner(new FileReader("input.text"));&nbsp; &nbsp; List<String> arrayType = new ArrayList<>(100);&nbsp; &nbsp; List<String> linkedType = new LinkedList<>();&nbsp; &nbsp; while (in.hasNext()){&nbsp; &nbsp; &nbsp; &nbsp; String line = in.next();&nbsp; &nbsp; &nbsp; &nbsp; arrayType.add(line);&nbsp; &nbsp; &nbsp; &nbsp; linkedType.add(line);&nbsp; &nbsp; }&nbsp; &nbsp; System.out.println(arrayType);}
