The Callable interface is similar to {@link * java.lang.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 {@link Executors} class contains utility methods to
* convert from other common forms to Callable classes.
