Answer 1

You could not do that without iterator, you should you Hashmap for this.

public class ObjectStructure{
private int Id;
private String name;
//and any data field you need
}

generate all setters and getters.

Use this class in

Hashmap data = new HashMap<>();

you can add and delete data with only key which is Integer.

data.remove(10);
