我有以下类型的哈希图:
private HashMap<String, HashMapObject> likesYearHashMap;
其中HashMapObject:
public class HashMapObject {
private int count;
private String id;
public HashMapObject(int count, String id) {
super();
this.count = count;
this.id = id;
}
}
如何将值转换为我的HashMap到HashMapObject []数组?
我得到强制转换的错误,得到likesYearHashMap.values();
最佳答案
像这样:
map.values().toArray(new HashMapObject[map.size()])
