Java - create ArrayList of Objects

0 points
Created by:

In this article, we would like to show you how to create ArrayList of Objects in Java.

Quick solution:

List<MyObject> object = new ArrayList<>();


Practical example

In this example, we create ArrayList of User objects 

import java.util.*;

public class Example {

    public static void main(String[] args) {
        //create User objects
        User user1 = new User("Tom", 24);
        User user2 = new User("Kate", 21);

        // create Array
        List<User> users = new ArrayList<>();

        // add items to the ArrayLists



[{name='Tom', age=24}, {name='Kate', age=21}]

User class:

public class User {
    private final String name;
    private final int age;

    public User(String name, int age) { = name;
        this.age = age;

    public String getName() {
        return name;

    public int getAge() {
        return age;

    public String toString() {
        return "{" +
                "name='" + name + '\'' +
                ", age=" + age +


We are able to print users in the Example class, because we have overridden toString() method in the User class.
