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 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 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]
