我是Java和Android开发方面的法国初学者。其实我尝试做运动,但是我被困住了...
我有一个对象(播放器)的ArrayList(playersList2),播放器包含字符串(mFirstName)和int(mScore))
我尝试了收集,循环,并阅读了许多文档和论坛,但找不到解决方案,但是我敢肯定这很容易
Players players = new Players(mFirstname, mScore);
mPreferences = getSharedPreferences(PREF_PLAYERS_LIST, MODE_PRIVATE);
String fromJsonPlayersList = mPreferences.getString(PREF_PLAYERS_LIST, null);
Gson gson = new Gson();
ArrayList<Players> playersList2 = gson.fromJson(fromJsonPlayersList, new TypeToken<ArrayList<Players>>()
{
}.getType());
/* find the weakiest players/
if //mscore is bigger than weakest players
{//remove the weakest players and add this one
}*/
我想在整个ArrayList中找到最小的mScore来创建条件(如果当前mScore>最小playersList2被当前Player替换为最弱的PlayersList2,则为Players)
非常感谢
最佳答案
对您而言,最简单的解决方案是使用简单的for循环,例如:
Players minScorePlayer = playersList2.get(0);
for (Players player: playersList2) {
if (player.getScore() < minScorePlayer.getScore()) {
minScorePlayer = player;
}
}
//now minScorePlayer variable contains the reference to a player with the minimal score
