Importing someone's Twitter feed
Main is just a driver program. Separate it from the implementation class.
If the called function throws an exception , someone has to handle it. Check who should do it and log some helpful message.
Variable name temp , temp2.
Could we guarantee that user!=null or temp!=null or it may not contain a null status i.e check for user!=null , temp!=null and status!=null.
No hard-coded value.
Make the twit extraction implementation generic for any pageSize, any user, i.e take that as input parameters or member variable and feed on it.
Since the Twit extraction API may be called by anyone, so have the username correction logic there itself.
Limit the printlns for debugging purpose only.
