Java Создание строкового массива от пользователя

Вот решение, использующее ArrayList для хранения имен команд:

import java.util.ArrayList;
import java.util.List;
import java.util.Scanner;

Вывод:

Enter number of teams:
3
Enter number of weeks:
2
Enter team 1 name 
MyTeam1
Enter score for team 1 on week number 1
1
Enter score for team 1 on week number 2
2
Enter team 2 name 
MyTeam2
Enter score for team 2 on week number 1
3
Enter score for team 2 on week number 2
4
Enter team 3 name 
MyTeam3
Enter score for team 3 on week number 1
4
Enter score for team 3 on week number 2
6
Team MyTeam1 Weeks: 1 2  Ave = 1
Team MyTeam2 Weeks: 3 4  Ave = 3
Team MyTeam3 Weeks: 4 6  Ave = 5
Week averages: 
Week 1 Ave = 2 Week 2 Ave = 4
