使用java读取UTF-8编码文本文件 [英] reading text file with utf-8 encoding using java

问题描述

我有使用utf-8编码阅读文本文件的问题
我正在使用java与netbeans 7.2.1平​​台

我已经配置了java项目处理UTF-8
javaproject ==>右键单击==>属性==>源==> UTF-8

但仍然获取未知字符输出：

代码：

 文件fileDirs = new File（C：\\file.txt）; 
 
 BufferedReader in = new BufferedReader（
 new InputStreamReader（new FileInputStream（fileDirs），UTF-8））; 
 
 String str; 
 
 while（（str = in.readLine（））！= null）{
 System.out.println（str）; 
} 
  

任何其他想法？

谢谢

解决方案

使用

  import java.io.BufferedReader; 
 import java.io.File; 
 import java.io.FileInputStream; 
 import java.io.IOException; 
 import java.io.InputStreamReader; 
 import java.io.UnsupportedEncodingException; 
 public class test {
 public static void main（String [] args）{
 
 try {
 File fileDir = new File（PATH_TO_FILE）; 
 
 BufferedReader in = new BufferedReader（
 new InputStreamReader（new FileInputStream（fileDir），UTF-8））; 
 
 String str; 
 
 while（（str = in.readLine（））！= null）{
 System.out.println（str）; 
} 
 
 in.close（）; 
} 
 catch（UnsupportedEncodingException e）
 {
 System.out.println（e.getMessage（））; 
} 
 catch（IOException e）
 {
 System.out.println（e.getMessage（））; 
} 
 catch（异常e）
 {
 System.out.println（e.getMessage（））; 
} 
} 
} 
  

您需要将UTF- 8在引号

I have problem in reading text file with utf-8 encoding I'm using java with netbeans 7.2.1 platform

I already configured the java project to handle UTF-8 javaproject==>right click==>properties==>source==>UTF-8

but still get the unknown character output: ����� �������� ���� �

the code:

File fileDirs = new File("C:\\file.txt");

BufferedReader in = new BufferedReader(
new InputStreamReader(new FileInputStream(fileDirs), "UTF-8"));

String str;

while ((str = in.readLine()) != null) {
    System.out.println(str);
}

any other ideas?

thanks

Use

    import java.io.BufferedReader;
    import java.io.File;
    import java.io.FileInputStream;
    import java.io.IOException;
    import java.io.InputStreamReader;
    import java.io.UnsupportedEncodingException;     
    public class test {
    public static void main(String[] args){

    try {
        File fileDir = new File("PATH_TO_FILE");

        BufferedReader in = new BufferedReader(
           new InputStreamReader(new FileInputStream(fileDir), "UTF-8"));

        String str;

        while ((str = in.readLine()) != null) {
            System.out.println(str);
        }

                in.close();
        } 
        catch (UnsupportedEncodingException e) 
        {
            System.out.println(e.getMessage());
        } 
        catch (IOException e) 
        {
            System.out.println(e.getMessage());
        }
        catch (Exception e)
        {
            System.out.println(e.getMessage());
        }
    }
}

You need to put UTF-8 in quotes
