1. String --> InputStream

InputStream convertToInputStream(String str)
{
        ByteArrayInputStream is = new ByteArrayInputStream(str.getBytes());
        return is;
}

2. InputStream --> String
    
String convertToString(InputStream is)
{
      
       BufferedReader in = new BufferedReader(new InputStreamReader(is));
        StringBuffer buffer = new StringBuffer();
        String line = "";
        while ((line = in.readLine()) != null)
        {
             buffer.append(line);
         }
         return buffer.toString();
           
}

When I do the socket programming, I always need to deal with inputstream and string, above are the basic ways to so that, but I am not sure if there are any simpler ways to do that...
