All Implemented Interfaces:
Executor

  • Method Details

    • execute

      public void execute(Runnable task)
      The execute method is used to queue the task for execution. If all threads are busy the provided task is queued and waits until all current and outstanding tasks are finished.
      Specified by:
      execute in interface Executor
      Parameters:
      task - this is the task to be queued for execution
