如何从同一个JSONObject获取多个字符串？
[英]How to get multiple strings from same JSONObject?

我需要得到所有这些，但现在他们都来自一个变量（“wtfbo”）。
@SuppressWarnings("rawtypes")
Map json1 = (Map) parser.parse(matei);
JSONObject wtf1 = (JSONObject) json1;
Long kiwi = (Long) wtf1.get("gameQueueConfigId");
JSONArray eat = (JSONArray) wtf1.get("participants");
Iterator<?> it = eat.iterator();
while (it.hasNext()) {
JSONObject dash = (JSONObject) it.next();
Long wtfbo = (Long) dash.get("summonerId");
System.out.println(wtfbo);
}
当我运行它时，他返回（注意这些值在一个Long变量“wtfbo”中）
2833743
2883696
1356728
653768
633003
458902
1513707
531086
891096
2982516
但我需要每个都以字符串/变量分隔。 用其他的话说，我需要那个
Long a = 2833743
Long b = 2883696
Long c = 1356728
Long d = 653768
Long e = 633003
Long f = 458902
Long g = 1513707
Long h = 531086
Long i = 891096
Long j = 2982516
Ps：抱歉英文不好

假设您需要处理任意数字，则需要使用Collection。 您没有说明任何特定要求，因此我假设您只是想按照它们在JSON中出现的顺序访问它们。
List<Long> summonerIds = new ArrayList<Long>(); // <== list to store summonerIds
while (it.hasNext()) {
JSONObject dash = (JSONObject) it.next();
summonerIds.add((Long) dash.get("summonerId")); // <== save
}
System.out.println(summonerIds.get(0)); // 1st <== access later
System.out.println(summonerIds.get(2)); // 3rd etc.
如果您确实需要通过“a”，“b”等访问，则可以使用Map实现此目的
Map<String, Long> summonerIds = new HashMap<String, Long>();
int i = 0;
while (it.hasNext()) {
JSONObject dash = (JSONObject) it.next();
summonerIds.put(Character.toString((char) ('a' + i)), (Long) dash.get("summonerId"));
}
System.out.println(summonerIds.get("a")); // 1st
System.out.println(summonerIds.get("c")); // 3rd etc.
