获取对象的最大值

Question

我有点问题。我从多个Beacon获取数据，然后将其放入arrayList中。现在我想要返回最近的那个。

{{1}}

Answer 1

Beacon nearest = null;
double distance = Double.MAX_VALUE;
for (Beacon beacon: arrayList){
  double maxDistance = beacon.getDistance();
  if (maxDistance < distance) {
    distance = maxDistance;
    nearest = beacon;
  }
}
