/**
* {@code Executable} is a functional interface that can be used to
* implement any generic block of code that potentially throws a
* {@link Throwable}.
*
* The {@code Executable} interface is similar to {@link java.lang.Runnable},
* except that an {@code Executable} can throw any kind of exception.
*
*
Rationale for throwing {@code Throwable} instead of {@code Exception}
*
* Although Java applications typically throw exceptions that are instances
* of {@link java.lang.Exception}, {@link java.lang.RuntimeException},
* {@link java.lang.Error}, or {@link java.lang.AssertionError} (in testing
* scenarios), there may be use cases where an {@code Executable} needs to
* explicitly throw a {@code Throwable}. In order to support such specialized
* use cases, {@link #execute()} is declared to throw {@code Throwable}.
