AbstractList remove() Method in Java with Examples

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]
