Can I create a lot of instance with the same name?

Question

I have, for a project in my studies, to create a map for an adventure game. I must create monsters on this map. For this I use a class that I called Creature. In my class Map i have to initialise the monsters but I
choose their quantity with Math.random() so I don't know how much the map will contain. If in a loop I do: Creature monster = new Creature(); will I have different instances with the same name(I doubt)? Will I have one monster re-created in each iteration of the loop? How can I do to have different monsters in different places (my map is a matrix 2x2)?

Answer 1

You would have many Creature references made, but only one variable to hold them, and it would go out of scope outside your loop. You could create a Creature array or use a List (both defined outside your loop) - as
// array
int numCreatures = randomGeneratedCreatureQuantity();
Creature[] monsters = new Creature[numCreatures];
for (int j = 0; j < numCreatures; j++) {
    monsters[j] = new Creature();
// Or a list
int numCreatures = randomGeneratedCreatureQuantity();
ArrayList monsters = new ArrayList();
for (int j = 0; j < numCreatures; j++) {
    monsters.add(new Creature());
}Good luck
