Since adding the array[facts] it is grayed out, and when I tried to add facts.length, facts is red, wont be recognized

String[] facts = {
                         "Ants stretch when they wake up in the morning.",
                         "Ostriches can run faster than horses.",
                         "Olympic gold medals are actually made mostly of silver.",
                         "You are born with 300 bones; by the time you are an adult you will have 206.",
                         "It takes about 8 minutes for light from the Sun to reach Earth.",
                         "Some bamboo plants can grow almost a meter in just one day.",
                         "The state of Florida is bigger than England.",
                         "Some penguins can leap 2-3 meters out of the water.",
                         "On average, it takes 66 days to form a new habit.",
                         "Mammoths still walked the earth when the Great Pyramid was being built." };
                }
            // The button was clicked so update the fact label with a new fact
                String fact = "";
                //Randomly select a fact
                Random randomGenerator = new Random(); //Construct a new Random number generator
                int randomNumber = randomGenerator.nextInt(facts.length);
