How to execute specific statements based on a random number generation? I'm using Java.

Answer 1

Alessio: Define your Strings and then use Math.random to choose the String.
E.g.

// random int from 0 to 9
int rand = (int)(Math.random() * 10);

switch (rand) {
case 0: // do something with 1. String
break;
// same for cases from 1 to 9
};

Consider using e.g. HashMap, that allows to store key/value pairs so you could access your String values by an int key. You only need to pass the rand from example above:
map.get(rand);
No need for switch statement then.

Answer 2

Use Math.random() and if/then/else?

Answer 3

Math.random() is a possibility then.
