Remarks
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 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 Executors
class contains utility methods to convert from other common forms to Callable
classes.
Added in 1.5.
