public class RandomListItem {
public static  Random random = new Random();
public static void main(String[] args) {
    List list = new ArrayList();
    int i = 0;
    while(i<3){
        list.add(i+"");
        i++;
    }
    for(String item: list){
        System.out.println(item);
    }
    System.out.println("----");
    int j = 0;
    while(j<12){
        j++;
        System.out.println(list.get(random.nextInt(list.size())));
    }
