Two different ArrayList merge? [closed]

Answer 1

If there are any realtionships between SublistLocalData class and the Localdata class you can create a class that is a super class both of them or an Interface which the two classes implements. Say you have this class : class AbstractSuperClass {} Then : Here how to declare a list of the superClass : List list; Using this list, you can add any type of AbstractSuperClass (classes that inherits from it like SublistLocalData and Localdata ) You can then write :

list.add(new SublistLocalData());

orlist.add(new Localdata());
