Java:如何按顺序返回多个对象？

Question

我正在尝试让智能智能体右转3次。既然不能返回多个对象，怎么能连续调用this.buildPhysicalAction(TurnRightAction.class) 3次呢？

public class VacuumWorldExplorerMind extends VacuumWorldDefaultMind {

  @Override
  public EnvironmentalAction decide(Object... parameters) {

    PerceiveAction range = new PerceiveAction();
    VacuumWorldCoordinates currentLocation;

    this.buildPhysicalAction(TurnRightAction.class);
    this.buildPhysicalAction(TurnRightAction.class);
    this.buildPhysicalAction(TurnRightAction.class);

    while (true) {

      // if perceive range-checkForWall == 1
      // turn left
      // count steps made = stepsMade
      if (range.getPerceptionRange() == 1) {
        return this.buildPhysicalAction(TurnLeftAction.class);
      }

      return this.buildPhysicalAction(MoveAction.class);
    }
  }
}

这基本上是一种设计选择。一种方法是定义如下类: TurnRightTwiceAction和TurnRightThriceAction，并在需要转一次、两次或三次时分别调用它们。

另一种选择是您已经在做的事情，调用TurnRightAction操作所需的次数。
