        System.out.println(people.get(1));
        System.out.println(people.get(2));
    }
}

You can print one by one without using loop but the problem is because you are using object type so you cannot print objects unless you use a toString method in the class even if you don’t use Arraylist it wont work if you want to print object, unless you use toString method

    class Main
    {
        public static void main(String[] args)
        {  
            ArrayList<Integer> arrayList = new ArrayList<Integer>();
            arrayList.add(6);
            arrayList.add(3);
            arrayList.add(5);

            System.out.println(arrayList.get(0));
            System.out.println(arrayList.get(1));
            System.out.println(arrayList.get(2));
        }
    }
