Java读写txt文件中文乱码有关问题


Java读写txt文件中文乱码问题

  问题:在用Java程序进行读写含中文的txt文件时,经常会出现读出或写入的内容会出现乱码。原因其实很简单,就是系统的编码和程序的编码采用了不同的编码格式。通常,假如自己不修改的话,windows自身采用的编码格式是gbk(而gbk和gb2312基本上是一样的编码方式),而IDE中Encode不修改的话,默认是utf-8的编码,这就是为什么会出现乱码的原因。当在OS下手工创建并写入的txt文件(gbk),用程序直接去读(utf-8),就会乱码。为了避免可能的中文乱码问题,最好在文件写入和读出的时候显式指定编码格式。

  1、写文件:

  public static void writeFile(String fileName, String fileContent) 

  {  

  try 

  {   

  File f = new File(fileName);   

  if (!f.exists()) 

  {   

  f.createNewFile();   

  }   

  OutputStreamWriter write = new OutputStreamWriter(new FileOutputStream(f),"gbk");   

  BufferedWriter writer=new BufferedWriter(write);     

  writer.write(fileContent);   

  writer.close();  

  } catch (Exception e) 

  {   

  e.printStackTrace();  

  } 

  } 

  public static void writeFile(String fileName, String fileContent)

  {

  try

  2、读文件:

  public static String readFile(String fileName)

  {

  String fileContent = ""; 

  try 

  {   

  File f = new File(fileName);   

  if(f.isFile()&&f.exists()) 

  {   

  InputStreamReader read = new InputStreamReader(new FileInputStream(f),"gbk");   

  BufferedReader reader=new BufferedReader(read);   

  String line;   

  while ((line = reader.readLine()) != null) 

  {    

  fileContent += line;   

  }    

  read.close();   

  }  

  } catch (Exception e) 

  {    

  e.printStackTrace();  

  }  

  return fileContent; 

  } 

  public static String readFile(String fileName)

  {

  String fileContent = "";

  try

  {

  File f = new File(fileName); 

  if(f.isFile()&&f.exists())

  {

  InputStreamReader read = new InputStreamReader(new FileInputStream(f),"gbk");

  BufferedReader reader=new BufferedReader(read);

  String line;

  while ((line = reader.readLine()) != null)

  {  

  fileContent += line;

  }

  read.close(); 

  }

  } catch (Exception e)

  {

  e.printStackTrace();

  }

  return fileContent;

  }
