Find SubList of ArrayList

In the previous post, we have seen how to sort the arrayList by using comparable and comparator.In this post, we will see how to get a sublist from a ArrayList.

Find SubList of ArrayList:

We have method called ‘sublist’ where we can define the range of sublist which needs to be acquired.


List subList(int fromIndex, int toIndex)

fromIndex: Start position of the range

toindex: End position of the range

Sublist method returns a type of list, so to store a list into arraylist we need to type cast the returned value. If list gets stored in the List directly , then there is no need to typecast.

It will be more clear with the below example.


List of total fruits: [Orange, Mango, Apple, Grapes, Banana] SubList of fruits stored in arrayList : [Apple, Grapes] SubList of fruits stored in List directly : [Apple, Grapes]

The subList method throws IndexOutOfBoundsException – if the specified indexes are out of the range of ArrayList (fromIndex < 0 || toIndex > size).
IllegalArgumentException – if the starting index is greater than the end point index (fromIndex > toIndex).
