推荐在Java中将同步方法转换为异步方法的更好方法

建议这样做：

abstract public class Action<T> implements Runnable {  private final T param;  public Action(T param) {    this.param = param;  }  @Override  public final void run() {    work(param);  }  abstract protected void work(T param);}

与：

ExecutorService exec = Executors.newSingleThreadExecutor();while () {  exec.submit(action);}exec.shutdown();exec.awaitTermination(Long.MAX_VALUE, TimeUnit.MILLISECONDS);
