Interface Callable<V>

  • Type Parameters:
    V - the result type of method call
    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.


    @FunctionalInterface
    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.
