Package Summary Overview Summary

### class:Callable [NONE]
Type Parameters: `V` - the result type of method `call` All Known Subinterfaces: `DocumentationTool.DocumentationTask`, `JavaCompiler.CompilationTask` All Known Implementing Classes: `JavacTask` 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. Since: 1.5 See Also: `Executor`

### method:call() [NONE]
### call V call() throws Exception Computes a result, or throws an exception if unable to do so. Returns: computed result Throws: `Exception` - if unable to compute a result
