Answer 1

yes by chosing the index of the myNames array randomly

Answer 2

you must put the r = rn.nextInt(3);
in side the for loop not out side in oder to get new random number each time.

otherwise, you will get the same result

import java.util.Random;

public class Program {
public static void main(String[] args) {
String[ ] myNames = { "Fred", "Tom", "George", "Tina"};

Random rn = new Random();
int r ;
for(int i= 0; i<=3; i++){
r = rn.nextInt(3);
System.out.println(myNames[i] + " is " + r);
}
}
}

Answer 3

rn.nextInt (x); for every name
