In this arraylist, there are four lists, each list containing six objects. The objects in the first list are the first objects in the arraylist. The objects in the second list are the second objects in the arraylist. The objects in the third list are the third objects in the arraylist. And the objects in the fourth list are the fourth objects in the arraylist.
The arraylist is basically like a list of lists, but with one big difference: each list has only one element. In other words, if you were to use an arraylist to store a list of lists like you could with an array, then each list could have only one element. This is the difference between an array list and a list of lists.
While an arraylist is a list of lists, a list of lists in the same way an array is a list of arrays. The difference is that with an arraylist you can add another list as long as it is in the same element of the first list as the first list. Whereas with a list of lists all the elements in the list must be in the same element of the first list.
So for example, let’s say you have an arraylist of lists. You can say you want to add the contents of list2 to the first element of list1, with the contents of list2 being in the same element of list1 as list1.
Now lets say that list2 contains a list of lists of arrays, and you want to add the contents of list3 to the first element of list2.
The problem with arraylist sets is that in general you don’t have to know the contents of each element in the arraylist, but you can easily give each element of the arraylist a value.
So in arraylist set, there is an element of an arraylist and a value. For example, list1 is a list of lists of arrays. Its first element is a list of list2. Now list2 has a list of lists of arrays. Its first element is a list of list3, which is a list of arrays.
arraylist sets are very useful in situations like ours where you dont know the contents of each element in the arraylist but you can identify its value.
