An array stores a fixed-size sequential collection of elements of the same type.
// An array is a succession of values of the same type
// Create an array

// The index number in an array starts with 0.
//Access the elements in an array
System.out.println(iceCreamFlavours[0]);
// the value listed is Cherry
// To get the length of an array use .length
System.out.println(iceCreamFlavours.length);
// To access the elements in an array
for (int i = 0; i < iceCreamFlavours.length; i++) {
