Java in a Nutshell, 5th Edition [Electronic resources] نسخه متنی

This interface is a generalized form of the
java.lang.Runnable interface. Unlike the
run( ) method of Runnable, the
call( ) method of Callable can
return a value and throw an Exception.
Callable is a generic type, and the type variable
V represents the return type of the
call( ) method.

An ExecutorService accepts
Callable objects for asynchronous execution and
returns a Future object representing the future
result of the call( ) method.
