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