- Functional Interface:
- This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
@FunctionalInterface public interface Callable<V>
A task that returns a result and may throw an exception. Implementors define a single method with no arguments calledcall.The
Callableinterface is similar toRunnable, in that both are designed for classes whose instances are potentially executed by another thread. ARunnable, however, does not return a result and cannot throw a checked exception.The
Executorsclass contains utility methods to convert from other common forms toCallableclasses.- Since:
