java集合compare去重_Java集合去重

//普通集合List去重方法

public List removethesame(List list) {

//创建一个临时集合装去重后的数据

List tempList = new ArrayList();

for (floorMapper i : list) {

if (!tempList.contains(i)) {//判断是否有重复数据，如果没有就将数据装进临时集合

tempList.add(i);

}

}

return tempList;

}

//根据Java中集合中根据对象的某个属性去重

private static List removeDuplicateFlight(List flights) {

Set set = new TreeSet(new Comparator() {

@Override

public int compare(floorMapper o1, floorMapper o2) {

//字符串,则按照asicc码升序排列

return o1.getFloorid().compareTo(o2.getFloorid());

}

});

set.addAll(flights);

return new ArrayList(set);

}
