java - nextLine() 扫描仪 java 无法正常工作(可能是因为 Unicode)

Question

我在文件中有一个字符串，应该按以下方式使用 Scanner 类中的 nextLine() 方法读取该字符串:

some_string = "All the staff in the operating room has been specifically trained with a theoretical and practical 20-hour course.\xe2\x80\xa9Results: The overall average incidence of adverse events reported was determined by 4.8%, is consistent with the expectations of the study protocol, and is at a lower level than the average median rate of international studies (8.9%).\n"

我通过以下方式创建扫描仪对象:

 Scanner br = new Scanner(new File("location of my file"), "UTF-8");

然后我通过执行以下操作得到下一行:

while (br.hasNextLine()) {
       System.out.println(br.nextLine());
}

我得到:

>All the staff in the operating room has been specifically trained with a theoretical and practical 20-hour course.
>Results: The overall average incidence of adverse events reported was determined by 4.8%, is consistent with the expectations of the study protocol, and is at a lower level than the average median rate of international studies (8.9%).

当存在非 ASCII 字符时，nextLine() 似乎会失败。有什么想法为什么会发生这种情况吗？

Answer 1

试试这个:

    Scanner scanner = new Scanner(new File("the file"), "UTF-8").useDelimiter("\n");

    while (scanner.hasNext())
        System.out.println(scanner.next());
