How to convert HashMap to own type array?

Question

I have my hash map of type:

private HashMap<String, HashMapObject> likesYearHashMap;

where HashMapObject :

public class HashMapObject {
private int count;
private String id;
public HashMapObject(int count, String id) {
 super();
 this.count = count;
 this.id = id;
}

}

how to convert values into my HashMap to HashMapObject [] array?

I get error of cast getting likesYearHashMap.values();

• Sotirios Delimanolis: Map#values() returns a Collection. Iterate over it and add its element to your array.

Answer 1

Like this:

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

Answer 2

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

Answer 3

Thanks to @Vakh and @NinChimpsky i post the complete solution:

To convert into array :

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

To convert to ArrayList

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