- Type Parameters:
V
- the result type of methodcall
- All Known Subinterfaces:
DocumentationTool.DocumentationTask
,JavaCompiler.CompilationTask
- Functional Interface:
- This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
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.
