Answer / venkat

implementing runnable interface is better than extending to
thread why because if u implements from runnable interface u
can have chance to extend one more class.but incase of
extending thread this facility is not there

Answer / mira

The Runnable technique is particularly convenient when you
want to create just a single thread to carry out a specific
task. The run() method will have access to the instance
variables in the Runnable object. For example, a common
approach to applet animation is to make the applet
Runnable. The run() method then has access to the applet's
variables, which could be parameters passed in the applet
tags or set by the user via the graphical interface.

Note also that since there are no restrictions on the
number of interfaces that a class can implement, it is easy
to add Runnable to a class.

On the other hand, if you want to create multiple threads,
then it usually makes more sense to use a Thread subclass.
This helps to better conceptualize the threads as
independent objects, each with its own independent sets of
variables (as opposed to sharing variables in the Runnable
object.) You can set the values of whatever parameters they
need via their constructors or "setter" methods.
