[JAVA基础]流文件读写文件编码转换

将本地的gbk文件流读取变换成utf-8文件

     public  static  void gbk2utf8(String targetFile,String outFile)
    {
        BufferedReader br =  null;
        BufferedWriter bw =  null;
         try
        {
            InputStream is =  new FileInputStream(targetFile);
            OutputStream os =  new FileOutputStream(outFile);
            br =  new BufferedReader( new InputStreamReader(is,"gbk"));
            String str = "";
            bw =  new BufferedWriter( new OutputStreamWriter(os,"utf-8"));
             while((str = br.readLine())!= null)
            {
                bw.write(str);
                bw.newLine();   
            }
        
        }  catch (Exception e)
        {
            e.printStackTrace();
        } 
         finally
        {
             try
            {
            
                 if( null!=bw)
                    bw.close();
                 if( null!=br)
                    bw.close();
            }  catch (IOException e)
            {
                 //  TODO Auto-generated catch block
                e.printStackTrace();
            }
        }
    }
