Java - Convert Array to ArrayList

By Preeti Jain Last updated : February 03, 2024

Problem statement

Given an array, you have to convert the given array to ArrayList using Java program.

Converting Array to ArrayList

To convert a given array to an ArrayList, you can use the Arrays.asList() method which is available in java.util package. This method accepts an array as its parameter and returns a list with array items (ArrayList).

Syntax

Below is the syntax to convert Array to ArrayList:

Java code to convert array to ArrayList

// Java program to demonstrate the example of
// conversion of an Array to an ArrayList with 
// the help of asList() method of Arrays

import java.util.*;

public class ArrayToArrayList {
  public static void main(String[] args) {
    // array declaration
    Integer arr[] = {
      10,
      20,
      30,
      40,
      50
    };

    // Display array elements 
    System.out.println("Array elements");
    for (int i = 0; i < arr.length; ++i)
      System.out.println(arr[i]);

    System.out.println();

    // By using asList() method is used to convert 
    // Array to ArrayList

    List arr_list = Arrays.asList(arr);

    // Display ArrayList
    System.out.println("ArrayList Elements:");
    System.out.println(arr_list);
  }
}

Output

The output of the above code is:

Array elements
10
20
30
40
50

ArrayList Elements:
[10, 20, 30, 40, 50]
