public interface Callable
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.
