According to the specification, which of the two, Runnable interface and Thread class, is preferred if you only intend to implement the run method? Why?

What will be an ideal response?


For good programming practice, the Runnable interface should be used if only the run method needs to be defined. A subclass of the Thread class should only be used if the program requires the modification or enhancement of the base class (that is, if the program needs to add variables and/or methods that are not in the Thread class).
