One technical cause is that Java does not support multiple inheritance. You cannot extend Thread when your class is already extending another. Another situation is when one who maintains the thread and one who provides the functionality are different � something like a generic thread pool.
One more reason is the coding style itself. People say if you "extend" a class you should be "adding" one or more functionalities to it. Such go for Runnable approach if the need is just to implement run() method.
