java：加速读取外来字符

Question

我目前的代码需要从网上读取外来字符，目前我的解决方案工作，但它非常慢，因为它使用InputStreamReader读char字符。无论如何要加快速度并完成工作？

// Pull content stream from response 
     HttpEntity entity = response.getEntity(); 
     InputStream inputStream = entity.getContent(); 

     StringBuilder contents = new StringBuilder(); 
     int ch; 
     InputStreamReader isr = new InputStreamReader(inputStream, "gb2312"); 
      // FileInputStream file = new InputStream(is); 
     while((ch = isr.read()) != -1) 
      contents.append((char)ch); 
     String encode = isr.getEncoding(); 

     return contents.toString(); 

Answer 1

与BufferedReader

包装你的InputStreamReader为 字符，数组和行的高效读取。

InputStreamReader isr = new InputStreamReader(inputStream, "gb2312"); 
Reader reader = new BufferedReader(isr);
