java - java: 加快读取外来字符

Question

我当前的代码需要从网上读取外来字符，目前我的解决方案可以工作，但速度很慢，因为它使用 InputStreamReader 逐字符读取。有没有办法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

用BufferedReader包装 InputStreamReader

用于高效读取字符、数组和行。

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