JAVA方法返回某条公交路线接载的总人数

Question

所以这是我的“Stop”类，其中有一个“station”类型的变量(该类与此事无关)和一个 int 变量“nPeople”，代表正在进入的人数该站公交车:

public class Stop {

    private Station station;
    private int nPeople;


    public Stop(Station station, int nPeople) {
        this.station = station;
        this.nPeople = nPeople;
    }


    public Station getStation() {
        return station;
    }
    public void setStation(Station station) {
        this.station = station;
    }

    public int getnPeople() {
        return nPeople;
    }
    public void setnPeople(int nPeople) {
        this.nPeople = nPeople;
    }
}

现在这是我的“Route”类，其中我有一个“Stop”类型的数组变量，它存储公共(public)汽车所经过的所有站点，使其成为公共(public)汽车路线，我想要一个方法“getTotalPeople”来返回总数巴士在一条路线上搭载的人数:

public class Route {


    private Station start;
    private Stop[] stops;

    public Route(Station start, Stop[] stops) {
        this.start = start;
        this.stops = stops;
    }

    public Station getStart() {
        return start;
    }

    public void setStart(Station start) {
        this.start = start;
    }

    public Stop[] getStops() {
        return stops;
    }

    public void setStops(Stop[] stops) {
        this.stops = stops;
    }



    public int getTotalPeople(){

    }

}

有什么想法如何返回“Stop[] Stops”数组的“nPeople”变量的总和吗？

Answer 1

public int getTotalPeople(){
  int total = 0;
  for(int i =0; i < stops.length ; i++){
       total += stops[i].getnPeople();
  }
  return total;
}
