从特定的包Java读取txt文件 [英] Reading txt file from a specific package Java

问题描述

我试图读取特定包中的文本文件，但返回无法找到。我可以读取它插入绝对路径，但我想读取它，而不插入绝对路径。

  String texto =Utils / CEP / Cidades /+ estado +.txt; 
 FileReader fr = new FileReader（texto）; 
 BufferedReader in = new BufferedReader（fr）; 
  

我应该怎么做？

解决方案

您可以使用

  InputStream in = 
 getClass（）。getResourceAsStream（/ Utils / CEP / Ciades /+ estado +.txt）; 
 Reader fr = new InputStreamReader（in，utf-8）; 
  

一些附注：不要在包名中使用大写字母;使用你的变量的英文名称。这些是被接受的做法和惯例。

I'm trying to read a text file in a specific package but it return that couldn't be found.I can read it inserting the absolute path but i want to read it without inserting the absolute path.

String texto = "Utils/CEP/Cidades/" + estado + ".txt";
FileReader fr = new FileReader(texto);
BufferedReader in = new BufferedReader(fr);

How should i do?

Thanks

解决方案

You can use

InputStream in = 
   getClass().getResourceAsStream("/Utils/CEP/Ciades/" + estado + ".txt");
Reader fr = new InputStreamReader(in, "utf-8");

A few sidenotes: don't use capital letters in package names; use English names of your variables. These are accepted practices and conventions.
