Interface Callable<V>
- Type Parameters:
V - the result type of method call
- All Known Subinterfaces:
- JavaCompiler.CompilationTask
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.
