In this article, we would like to show you how to convert an array to ArrayList in Java.

Quick solution:

String[] array = {"a", "b", "c"};
List<String> arrayList = new ArrayList<>(Arrays.asList(array));

 

Practical example

In these examples, we will show how to convert an array of Strings to the ArrayList.

Method 1 - using Arrays.asList()

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

public class Example {

    public static void main(String[] args) {
        String[] array = {"a", "b", "c", "d"};

        List<String> arrayList = new ArrayList<>(Arrays.asList(array));
        System.out.println(arrayList);
    }
}

output:

[a, b, c, d]

Method 2 - using Collections.addAll()

import java.util.Collections;
import java.util.ArrayList;
import java.util.List;

public class Example {

    public static void main(String[] args) {
        String[] array = {"a", "b", "c", "d"};

        List<String> arrayList = new ArrayList<>();
        Collections.addAll(arrayList, array);
        System.out.println(arrayList);
    }
}

output:

[a, b, c, d]
