Does enums support all data types?

Answer 1

No Enums in compile time are broken down to a list of numbers. Say you have and enumeration of {"Cat", "Dog", "Mouse"} when you use that in your application it will be stored as 0, 1, 2 integer values. Instead of being stored as strings.

Answer 2

Of course... you can overwrite the constrctor to provide more meaningful info

class Main {

public static void main(String[] args) {

Player player1 = new Player(Difficulty.EASY);
Player player2 = new Player(Difficulty.MEDIUM);
Player player3 = new Player(Difficulty.HARD);
}
}
enum Difficulty {
EASY(3000),
MEDIUM(2000),
HARD(1000);

public final int bullets;
private Difficulty(int bullets) {
this.bullets = bullets;
}
}

public class Player{
Player(Difficulty diff){
//your code goes here
int bullets = diff.bullets;
/*
switch (diff) {
case EASY:
bullets = 3000; break;
case MEDIUM:
bullets = 2000; break;
case HARD:
bullets = 1000; break;
}
*/

System.out.format("You have %d bullets", bullets);
}
}
