为什么剩余的居住人数计算不正确？

Question

我正在编写一个救援模拟程序，并且在应用所需的测试时，它一直失败，提示建筑物中剩余的居住人数没有正确计算，我不知道为什么！ 在下面，我提供了两种应该返还乘员人数的方法。 预先感谢！

public void treat(){
    boolean f=false;
    if(!f){
          ((Disaster)((Citizen)this.getTarget()).getDisaster()).setActive(false);
               ResidentialBuilding r= (ResidentialBuilding)this.getTarget();
              if(r.getOccupants().size()!=0){
                 for(int i=0;i<r.getOccupants().size();i++){
                     if(this.getPassengers().size()<=this.getMaxCapacity()){
                          f=true;
                          Citizen z=(Citizen)r.getOccupants().get(i);
                          if(z.getState()!=CitizenState.DECEASED){
                              r.getOccupants().remove(i);
                              this.getPassengers().add(z);
                          }    
                      }

                  }
              } 
              else{
                  this.setState(UnitState.IDLE);
                  this.jobsDone();
              }
          }
        else
            this.cycleStep();

        }   




    public void cycleStep(){
        if(super.getDistanceToBase()==0)
            super.getWorldListener().assignAddress(this, 0, 0);
        if(super.getTarget()!=null){
            if(this.getLocation()== this.getTarget().getLocation()){
                this.setDistanceToBase(this.getLocation().getX() + this.getLocation().getY());
            }
            else if(this.getDistanceToBase()<=0){
                this.setDistanceToBase(0);
                this.setLocation(new Address(0,0));
                for (int i = 0; i < this.getPassengers().size(); i++) {
                    Citizen c = (Citizen)this.getPassengers().remove(i);

                }
            }
            else{
                this.setDistanceToBase(this.getDistanceToBase()-this.getStepsPerCycle());
            }
        }
    }
