Random, Array and char in java

I need to take a random element from an array of chars

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.
