I need to take a random element from an array of `char`s

1. C for hearts
2. Q for diamonds
3. F for clubs
4. P for spades

```
Random casuale = new Random()

char[] arraySuits = {'c', 'c', 'c', 'q', 'q', 'q', 'f', 'f', 'f', 'p', 'p', 'p',};

location1S=casuale.next(arraySuits.length);
location2S=casuale.next(arraySuits.length);

```

There are two errors:

* Type mismatch: cannot convert from `int` to `char`
* The method `next(int)` from the type `Random` is not visible

The errors are both at `casuale.next(arraySuits.length)` but I don't know how to fix it.
