println(joinedAnimals); // Prints “cat : seal : bear”

// Joining an array of ints requires first

// converting to an array of Strings

int[] numbers = new int[3];

numbers[0] = 8;

numbers[1] = 67;

numbers[2] = 5;

String joinedNumbers = join(nf(numbers, 0), “, “);

println(joinedNumbers); // Prints “8, 67, 5”
