How do I access the thread lanSendThread from another class in another
file?

     The same way you'd access it if it were an ArrayList or
a JButton or a File: You save the reference somewhere and dish
it out to interested parties. There must be two or three jillion
ways to do this; a few of them are

     - Make `lanSendThread' a public member of the controller
       class (poor choice of name, by the way). You may or may
       not want to make that member `final'.

     - Make `lanSendThread' a private member of the controller
       class, and write a public getThread() method to return it.

     - Stash the value of `lanSendThread' in a Map or other data
       structure, and "publicize" the data structure and/or
       accessors for it.
