Created by:

In this article, we would like to show you how to create List with values initialized on creation in Java.

Quick solution:

List<Integer> numbers = Arrays.asList(1, 2, 3);
System.out.println(numbers);  // [1, 2, 3]


Practical example

In this example, we use Arrays.asList() method to add items to the list on its creation.

import java.util.Arrays;
import java.util.List;

public class Example {

    public static void main(String[] args) {
        List<Integer> numbers = Arrays.asList(1, 2, 3);
        System.out.println("Numbers: " + numbers);  // [1, 2, 3]

        List<String> letters = Arrays.asList("A", "B", "C");
        System.out.println("Letters: " + letters);  // [A, B, C]


Numbers: [1, 2, 3]
Letters: [A, B, C]
