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. toIndex – last index in existing arraylist. In Java, it is good practice to use interface types rather than concrete classes in APIs. Syntax. There are few important points regarding this method which I have shared at the end of this post. If the start index and the end index are the same, then an empty sub-list is returned. It is inclusive. Get sublist of arraylist example. Please note that any change made on objects in sublist will be reflected on original arraylist as well. toIndex − This is the high endpoint (exclusive) of the subList. 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: It is exclusive. 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.. This method eliminates the … However, in this article, we will mainly focus on ArrayList and LinkedList objects. This is what your code should look like: Passing True to the method which causes to include line public List subList(int fromIndex,int toIndex) Parameters. Points to Note in the below example: Java: split a List into two sub-Lists. 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. Vector Class subList() method. Java Vector subList() Method. The subList of a LinkedList can be obtained using the java.util.LinkedList.subList(). subList() method is available in java.util package. If fromIndex and toIndex are equal, the returned List is empty. 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. Java ArrayList.subList() – Examples. subList(int fromIndex, int toIndex) For example :. Suppose we need to sort an array of positive integers {3,11,2,9,1,5}. 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. 2. We are declaring an ArrayList of countries. 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. Example of the subList method on an ArrayList object. 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 … fromIndex − This is the low endpoint (inclusive) of the subList. Following is the declaration for java.util.Vector.subList() method. the start index for the sub-list(inclusive) and the end index for the sub-list(exclusive) from the required LinkedList. Java program to get a sublist of arraylist from an existing sublist. Return Value. 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). This method takes two parameters i.e. List subList(int fromIndex, int toIndex) Here fromIndex is inclusive and toIndex is exclusive. Example of getting sub-list from an ArrayList. We will be doing it using the subList method of ArrayList class. We are getting the sublist from index 2 to 6.
