AbstractList remove() Method in Java with Examples Last Updated : 26 Nov, 2018 Comments Improve Suggest changes Like Article Like Report The remove(int index) method of java.util.AbstractList class is used to remove an element from an abstract list from a specific position or index. Syntax: AbstractList.remove(int index) Parameters: The parameter index is of integer data type and specifies the position of the element to be removed from the AbstractList. Return Value: This method returns the element that has just been removed from the list. Below programs illustrate the AbstractList.remove(int index) method: Program 1: Java // Java code to illustrate remove() method import java.util.*; import java.util.LinkedList; public class AbstractListDemo { public static void main(String args[]) { // Creating an empty AbstractList AbstractList<String> list = new LinkedList<String>(); // Using add() method to add elements in the list list.add("Geeks"); list.add("for"); list.add("Geeks"); list.add("10"); list.add("20"); // Output the list System.out.println("AbstractList: " + list); // Remove the head using remove() list.remove(3); // Print the final list System.out.println("Final AbstractList: " + list); } } Output: AbstractList: [Geeks, for, Geeks, 10, 20] Final AbstractList: [Geeks, for, Geeks, 20] Program 2: Java // Java code to illustrate remove() when position of // element is passed as parameter import java.util.*; import java.util.LinkedList; public class AbstractListDemo { public static void main(String args[]) { // Creating an empty AbstractList AbstractList<String> list = new LinkedList<String>(); // Use add() method to add elements in the list list.add("Geeks"); list.add("for"); list.add("Geeks"); list.add("10"); list.add("20"); // Output the list System.out.println("AbstractList:" + list); // Remove the head using remove() list.remove(0); // Print the final list System.out.println("Final AbstractList:" + list); } } Output: AbstractList:[Geeks, for, Geeks, 10, 20] Final AbstractList:[for, Geeks, 10, 20] Comment More infoAdvertise with us Next Article AbstractList remove() Method in Java with Examples C chinmoy lenka Follow Improve Article Tags : Misc Java Java-Collections Java - util package Java-Functions Java-AbstractList +2 More Practice Tags : JavaJava-CollectionsMisc Similar Reads AbstractList in Java with Examples The AbstractList class in Java is a part of the Java Collection Framework and implements the Collection interface and the AbstractCollection class.
