How to convert a Map to List in Java?

Question

What is the best way to change a Map<key, value> to a List<value>? Just iterate over every value and insert them in a list or am I overlooking something?

Answer 1

The problem here is that Map has two values (a key and value), while a List only has one value (an element).

Hence, the best that can be done is to either get a List of the keys or the values:

List<Value> list = new ArrayList<Value>(map.values());
