title: Should I use threads when making a text based operating system in java?
body: <p>I am making text based operating system in java and i am wondering if i should use threads.
  It has a GUI but you type commands and press a button to enter them. Then it spits back out text in a textArea. When should i use threads and how do i use them? Do i need to use threads? I don't really know how to use them and when to use them!</p>
