List remove(int index) method in Java with Examples

The remove(int index) method of List interface in Java is used to remove an element from the specified index from a List container and returns the element after removing it. It also shifts the elements after the removed element by 1 position to the left in the List.

Syntax:

E remove(int index)

Where, E is the type of element maintained
by this List collection

Parameters: It accepts a single parameter index of integer type which represents the index of the element needed to be removed from the List.

Return Value: It returns the element present at the given index after removing it.

Below program illustrate the remove(int index) method of List in Java:

Program 1:

// Program to illustrate the
// remove(int index) method

import java.util.*;

public class GFG {
    public static void main(String[] args)
    {

        // Declare an empty List of size 5
        List<Integer> list = new ArrayList<Integer>(5);

        // Add elements to the list
        list.add(5);
        list.add(10);
        list.add(15);
        list.add(20);
        list.add(25);

        // Index from which you want to remove element
        int index = 2;

        // Initial list
        System.out.println("Initial List: " + list);

        // remove element
        list.remove(index);

        // Final list
        System.out.println("Final List: " + list);
    }
}

Output:

Initial List: [5, 10, 15, 20, 25]
Final List: [5, 10, 20, 25]

Program 2:

// Program to illustrate the
// remove(int index) method

import java.util.*;

public class GFG {
    public static void main(String[] args)
    {

        // Declare an empty List of size 5
        List<String> list = new ArrayList<String>(5);

        // Add elements to the list
        list.add("Welcome");
        list.add("to");
        list.add("Geeks");
        list.add("for");
        list.add("Geeks");

        // Index from which you want
        // to remove element
        int index = 2;

        // Initial list
        System.out.println("Initial List: " + list);

        // remove element
        list.remove(index);

        // Final list
        System.out.println("Final List: " + list);
    }
}

Output:

Initial List: [Welcome, to, Geeks, for, Geeks]
Final List: [Welcome, to, for, Geeks]
