java - 根据键值对对象进行排序

Question

我有一个 ArrayList，其中包含 CricketLiveScore 对象

  CricketLiveScore{
     String homeAbbrevation;
   }

   List myList=new ArrayList<CricketLiveScore>();
   CricketLiveScore c1=new CricketLiveScore();
   c1.setHomeAbbrevation("IND vs PAK");
   CricketLiveScore c2=new CricketLiveScore();
   c2.setHomeAbbrevation("SRI vs NWZ");
   CricketLiveScore c3=new CricketLiveScore();
   c3.setHomeAbbrevation("AUS vs BAN");
   CricketLiveScore c4=new CricketLiveScore();
   c4.setHomeAbbrevation("NWZ vs IND");

   list.add(c1);
   list.add(c2);
   list.add(c3);
   list.add(c4);

我需要根据主页缩写中的值为 IND 的对象对这个 Arraylist 进行排序 有人可以帮忙解决这个问题，以便我需要一个要排序的列表，并首先显示包含 IND 值的输出。

Answer 1

试试这个:

public class CricketLiveScoreComparator implements Comparator<CricketLiveScore> {
    @Override
    public int compare(CricketLiveScore c1, CricketLiveScore c2) {
        return c1.getHomeAbbrevation().compareTo(c2.getHomeAbbrevation());
    }
}

然后调用排序操作:

Collections.sort(myList, new CricketLiveScoreComparator());
