How to pick one random string from given strings?

Question

How can I make a program that will pick one random string from given strings like this:

int x;
x = Random.Range(0,2);
string[] Quest0 = {"You","Are","How","Hello"};
string[] Quest1 = {"Hey","Hi","Why","Yes"};
string[] Quest2 = {"Here","Answer","One","Pick"};

I would like to print out like this: if x = 2 it would print out Quest2 and so on.

Thank you!

Put Quest0, Quest1 and Quest2 in an array or List and use x as the index you print. — adamdc78, Nov 21 '14 at 20:31
do a google search! come on this is actually quite simple show some more effort.. here is an example I saved you some time http://stackoverflow.com/questions/6695187/pick-random-string-from-array — MethodMan, Nov 21 '14 at 20:33
"adamdc78" already told you how to do that. Are you asking how to code that?? :| — Md Ashaduzzaman, Nov 21 '14 at 20:34

Fistly you need to declare a random variable.

Random random = new Random();

this will create a variable in which you can now get random numbers from. to get random numbers you will use random.next(x,y) or in your case random.next(0,3) because the final argument is exclusive, so if you want 0, 1 or 2, you must use (0,3).

you then need to make some conditional statments, i would use If statments, to accomplish your goal use something like this:

 if (x == 2) 
        {
            foreach (string s in Quest2)
            {
                Console.WriteLine(s);
            }
        }

Do this for each possible outcome and it will print out all of the values in your array of strings. Hope I have been helpful, thanks.

List<String[]> quests = new ArrayList<String[]>();
quests.add(0, new string[]{"You","Are","How","Hello"});
quests.add(1, new string[]{"Hey","Hi","Why","Yes"});
quests.add(2, new string[]{"Here","Answer","One","Pick"});
int x = new Random().nextInt((2 - 0) + 1);
System.out.println(quests.get(x).toString());
