subList(int fromIndex, int toIndex) We are declaring an ArrayList of countries. Java: split a List into two sub-Lists. Example of getting sub-list from an ArrayList. This method eliminates the … This method takes two parameters i.e. fromIndex − This is the low endpoint (inclusive) of the subList. 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.. As a little note today, if you ever need to extract a subset of a Java list or array, here are some examples of the Java subList method: We are getting the sublist from index 2 to 6. 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 of a LinkedList can be obtained using the java.util.LinkedList.subList(). Points to Note in the below example: However, in this article, we will mainly focus on ArrayList and LinkedList objects. List subList(int fromIndex, int toIndex) Here fromIndex is inclusive and toIndex is exclusive. For example :. the start index for the sub-list(inclusive) and the end index for the sub-list(exclusive) from the required LinkedList. 2. Example of the subList method on an ArrayList object. List = [1,2,3,4,5,6] newList = List.subList(1,5) Since subList is a method of List interface, you can use it on ArrayList, LinkedList, Stack, and Vector objects. subList() method is available in java.util package. SubList elements from index 0(inclusive) to 3 (exclusive) : [10, 15] Removing elements from a List using subList() subList method eliminates the need for explicit range operations (of the sort that commonly exist for arrays). Following is the declaration of subList() method: toIndex − This is the high endpoint (exclusive) of the subList. Suppose we need to sort an array of positive integers {3,11,2,9,1,5}. public List subList(int fromIndex,int toIndex) Parameters. If fromIndex and toIndex are equal, the returned List is empty. Java Vector subList() Method. It is inclusive. toIndex – last index in existing arraylist. Java ArrayList.subList() – Examples. Please note that any change made on objects in sublist will be reflected on original arraylist as well. It is exclusive. 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. Get sublist of arraylist example. Vector Class subList() method. Following is the declaration for java.util.Vector.subList() method. In Java, it is good practice to use interface types rather than concrete classes in APIs. We will be doing it using the subList method of ArrayList class. Syntax. 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 program to get a sublist of arraylist from an existing sublist. Return Value. This is what your code should look like: Passing True to the method which causes to include line In this tutorial, we will learn about the Java ArrayList.subList() method, and learn how to use this method to get a sub list from the given ArrayList, with the help of examples. subList() method is used to return a set of sublist [it returns all those elements exists in a given range starting index (st_index) and ending index (en_index) and here st_index is inclusive … There are few important points regarding this method which I have shared at the end of this post.
