示例1: executeOrQueue
import org.threadly.concurrent.future.ListenableFuture; //导入方法依赖的package包/类
/**
* This is called once a task is ready to be executed (or if unable to execute immediately,
* queued). In addition to the task itself, this function takes in any future which represents
* task execution (if available, otherwise {@code null}). Passing in as a separate argument
* allows us to avoid a {@code instanceof} check, but does require it to be specified for
* pre-future listener completion support.
*
* @param task Task to be executed
* @param future Future to represent task completion or {@code null} if not available
