JSONObject 取前十

根据引用的代码示例，JSONObject的方法get(Object key)可以用来取出不存在的键值对时不会报异常，会返回null。因此，可以使用这个方法来获取JSONObject前十个键值对的值。具体实现可以参考以下代码示例：

JSONObject jSONObject = JSONObject.fromObject(map);
for(int i = 0; i < 10; i++) {
Object value = jSONObject.get(i);
System.out.println(value);
}<span class="em">1</span><span class="em">2</span><span class="em">3</span>
