Randomize different ArrayList to get a value

I searched for related questions but didn´t find a solution (at least i don´t know if i name it correctly)

So, i have two ArrayLists and i would like to randomize all of them to get a value:

public static ArrayList listOne(){


    ArrayList<> listOne = new ArrayList<>();
    listOne.add(new Team("Text One"));
    listOne.add(new Team("Text Two"));
    return listTwo;

}

   public static ArrayList listTwo(){


    ArrayList<> listTwo = new ArrayList<>();
    listTwo.add(new Team("Text Three"));
    listTwo.add(new Team("Text Four"));
    return listTwo;

}

my desired output would be one of the four listItems.

Appreciate the help!
