Java / Java Multithreading
Difference between Runnable and Callable interfaces in Java.
The Callable interface is similar to Runnable,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 unlike Callable which returns a result and throw exceptions.
