//对listResult进行排序,根据伴随度进行降序
List<FollowIMSI> collect = listResult.stream()
.sorted(Comparator.comparing(FollowIMSI::getFollowDegree).reversed())
.collect(Collectors.toList());
根据集合中对象FollowIMSI中的伴随度进行倒序排列…reversed(),默认正序,reversed反转后即倒序;
List<CollisionEntity> firstA = listEntity.stream()
.filter(collisionEntity -> collisionEntity.getMatchNums() >= 2)
.collect(Collectors.toList());
过滤,过滤掉collisionEntity中匹配次数多于两次的结果,firstA中存放的都是多于两次的
List<CollisionEntity> result = firstA.stream()
.sorted(Comparator.comparing(CollisionEntity::getMatchNums))
.collect(Collectors.toList());//根据matchnums排序
根据匹配次数正序排列,从小到大.
