Callable (Java Platform SE 7 ) (original) (raw)

• Type Parameters:
  V - the result type of method call
  All Known Subinterfaces:
  JavaCompiler.CompilationTask

public interface Callable
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. ARunnable, 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.
