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]
