[英]Reading lines from a file in Java
G'day: 天儿真好:
I'm trying to use this: 我正在尝试使用此:
List<String> lines = Files.readAllLines(Paths.get(path), encoding);
from https://stackoverflow.com/a/326440/2698254 and http://docs.oracle.com/javase/7/docs/api/java/nio/file/Files.html#readAllLines%28java.nio.file.Path,%20java.nio.charset.Charset%29 来自https://stackoverflow.com/a/326440/2698254和http://docs.oracle.com/javase/7/docs/api/java/nio/file/Files.html#readAllLines%28java.nio.file 。路径,%20java.nio.charset.Charset%29
but I'm having a bit of trouble implementing it. 但我在实施它时遇到了一些麻烦。
My goal is to read all the lines from a file, then do some stuff with each line using that list (I imagine it works just like a vector...) 我的目标是从文件中读取所有行,然后使用该列表对每一行进行一些处理(我想它的工作方式就像矢量一样)。
A few questions, because I'm getting a bunch of errors: 几个问题,因为我遇到了很多错误:
List<String> lines = Files.readAllLines(Paths.get("assets/unitsloc.txt"), Charset.defaultCharset());
This is what I've got so far, but the error markers are: 这是我到目前为止的内容,但是错误标记是:
"Files cannot be resolved" - but there's no useful suggested import to make, same with Paths. “文件无法解析”-但是没有建议进行有用的导入,与Paths相同。
"The type List is not generic: it cannot be parametrized with arguments " -Do I need to initialise lines first? “类型列表不是通用的:不能用参数进行参数设置”-我是否需要首先初始化行?
You need to import the class before using it. 您需要先导入该类,然后再使用它。
At the top of you class (after package), add 在课程的顶部(打包后),添加
import java.nio.file.Files;
import java.nio.file.Paths;
As readAllLines returns List<String>
the warning about this should go away after correct importation. 当readAllLines返回List<String>
,关于此的警告应在正确导入后消失。
