If the start index and the end index are the same, then an empty sub-list is returned. Your problem is that you are using ArrayList (probably in lots of places) where you should really be using List.As a result you created problems for yourself with an unnecessary constraint that the list is an ArrayList.. Java ArrayList.subList() – Examples. toIndex − This is the high endpoint (exclusive) of the subList. list.subList(from, to).clear(); Similar idioms may be constructed for indexOf and lastIndexOf, and all of the algorithms in the Collections class can be applied to a subList.

Java: split a List into two sub-Lists. Syntax. Java List sublist Method The sublist method of List Interface returns a view of the portion of this list between the inclusive and exclusive parameters. The subList() method of Java Vector class is used to get a view of the portion of the list between fromIndex, inclusive, and toIndex, exclusive. fromIndex − This is the low endpoint (inclusive) of the subList. Java program to get a sublist of arraylist from an existing sublist. This method takes two parameters i.e. We are getting the sublist from index 2 to 6. public List subList(int fromIndex,int toIndex) Parameters. This method eliminates the … toIndex – last index in existing arraylist.
