[Java]Array List

Ok i need help grabbing a random string from an arraylist.

I declared:

Code:

---

public static ArrayList<String> cZP = new ArrayList<String>();

---

And added this to the appropriate spot

Code:

---

cZP.add(name)

---

It adds it to the list fine, but I'm having trouble making it randomly select 1 of the usernames added to the list. I've tried a few things but keep getting errors.

You could try creating a random number between 0 and cZP.size(), then call cZP.get(number) using that random number - shouldn't give you errors really. What have you tried already and why did it not work?

Code:

---

int r = random(0, cZP.length);

string p = cZP[r];

---

should work?

That won't work, cZP[r] will give a compile-time error, you would need to use something like cZP.get(r), and also random() would need to be a separate method.

Try something like this.

Code:

---

ArrayList<String> cZP = new ArrayList<String>();
cZP.add("name");
cZP.add("name2");
...
int r = new Random().nextInt(cZP.size());
String name = cZP.get(r);

---

cZP.get(Math.Random(cZP.size()));

Shoould work, mate
