Create an ArrayList with multiple object types?

Question

How do I create an ArrayList with integer and string input types? If I create one as:

List<Integer> sections = new ArrayList <Integer>(); 

that will be an Integer type ArrayList. If I create one as:

List<String> sections = new ArrayList <String>(); 

that will be of String type. How can I create an ArrayList which can take both integer and string input types? Thank you.

Answer 1

You can make it like :

List<Object> sections = new ArrayList <Object>(); 

(Recommended) Another possible solution would be to make a custom model class with two parameters one Integer and other String. Then using an ArrayList of that object.

Answer 2

(1)

   ArrayList<Object> list = new ArrayList <>();`         list.add("ddd");    list.add(2);    list.add(11122.33);        System.out.println(list); 

(2)

 ArrayList arraylist = new ArrayList();  arraylist.add(5);          arraylist.add("saman");       arraylist.add(4.3);          System.out.println(arraylist);
