public static void main(String[] args) {
//Create an empty fruit and cost map
EnumMap<Fruit, Integer> enumMap = new EnumMap<Fruit, Integer>(Fruit.class);
//Populate map with fruit and its cost
for (int i = 0 ; i < Fruit.values().length ; i ++) {
enumMap.put(Fruit.values()[i], (i+1) * 100);
}
System.out.println("Fruit Map : " + enumMap);
System.out.println("Fruit Map Size : " + enumMap.size());
