Able to create subclasses and understand how they inherit from each other. If you want diferents list and diferent references, you must clone every object in a new list: public data class Person(var n: String)ĬloneNames.get(0). Able to define a Kotlin class, create an object instance from it, and access its properties and methods.
That's bacause you are adding all the object references to another list, hence you are not making a proper copy, you have the same elements in two list. I tried doing this, but it doesn't work: val oldList:ArrayList This is the object: class ClassA(var title: String?, var list: ArrayList, var selected: Boolean)Ĭlass ClassB(val id: Int, val name: String)
The returned list is backed by this list, so non-structural changes in the returned list are reflected in this list, and vice-versa. I am new to kotlin and I am trying to make a copy of a list of objects.The problem I am having is that when I change items in the new copy, the old list gets changed as well. subList Returns a view of the portion of this list between the specified fromIndex (inclusive) and toIndex (exclusive).
