How to Append an Element to a List in Java ?

Answer

To append an element to a list in Java, you can use the add method of the ArrayList class or any class that implements the List interface.

✐ Examples

1 Append an Element to an ArrayList

In this example,

We create an ArrayList named numbers with initial integer values.
We use the add method of the ArrayList numbers to append a new integer to the list.
The add method modifies the original list by adding the new element at the end.
Finally, we print the updated list to standard output.

Java Program

import java.util.ArrayList;

public class Main {
    public static void main(String[] args) {
        ArrayList<Integer> numbers = new ArrayList<>();
        numbers.add(1);
        numbers.add(2);
        numbers.add(3);
        numbers.add(4);
        numbers.add(5);
        System.out.println("Updated list: " + numbers);
    }
}

Output

Updated list: [1, 2, 3, 4, 5]

2 Append an Element to a LinkedList

In this example,

We create a LinkedList named numbers with initial integer values.
We use the add method of the LinkedList numbers to append a new integer to the list.
The add method modifies the original list by adding the new element at the end.
Finally, we print the updated list to standard output.

Java Program

import java.util.LinkedList;

public class Main {
    public static void main(String[] args) {
        LinkedList<Integer> numbers = new LinkedList<>();
        numbers.add(1);
        numbers.add(2);
        numbers.add(3);
        numbers.add(4);
        numbers.add(5);
        System.out.println("Updated list: " + numbers);
    }
}

Output

Updated list: [1, 2, 3, 4, 5]
