Convert Collection to List

Question

I would like to ask: how do you convert a `Collection` to a `List` in Java?

Accepted Answer

If you have already created an instance of your List subtype (e.g., ArrayList, LinkedList), you could use the addAll method.

e.g.,

```
l.addAll(myCollection)
```

Many list subtypes can also take the source collection in their constructor.
