如何将HashMap转换为自己的类型数组？

Question

我的哈希映射类型为：

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HashMap到HashMapObject []数组？

我得到了关于强制转换的错误:YearHashMap.values（）;

Answer 1

像这样：

map.values().toArray(new HashMapObject[map.size()])

Answer 2

likesYearHashMap.values().toArray (new HashMapObject[likesYearHashMap.size ()])

Answer 3

感谢@Vakh和@NinChimpsky，我发布了完整的解决方案：

要转换为数组：

HashMapObject[] array = new HashMapObject[likesYearHashMap.size()];
likesYearHashMap.values().toArray(array);

转换为ArrayList

Collection<HashMapObject> values = likesYearHashMap.values();
ArrayList<HashMapObject> arrayList= new ArrayList<HashMapObject>(values);
