Answer / divya
public interface Callable<V>A task that returns a result
and may throw an exception. Implementors define a single
method with no arguments called call.
The Callable interface is similar to Runnable, in that both
are designed for classes whose instances are potentially
executed by another thread. A Runnable, however, does not
return a result and cannot throw a checked exception.
The Executors class contains utility methods to convert
from other common forms to Callable classes.
