You use threads when you need multiple parts of your program running concurrently. Don't inherit Thread if all you are doing is a simple object with state, nor if your program does not need concurrency. --089e01537592ae31c404e47d01a6 Content-Type: text/html; charset=ISO-8859-1 Content-Transfer-Encoding: quoted-printable

I cannot tell whether you are trolling or are just new to th= is, but you don't always have to use threads. You use threads when you = need multiple parts of your program running concurrently. Don't inherit= Thread if all you are doing is a simple object with state, nor if your pro= gram does not need concurrency.
