How to Easily Convert Java Arrays to ArrayLists?

Easily Convert Arrays to ArrayLists using Java

Storing data in arrays is common in Java, but sometimes you may need to work with collections like ArrayLists. Creating an ArrayList from an array is a straightforward process.

Converting an Array to ArrayList

Consider an Element[] array contains Element objects:

Element[] array = {new Element(1), new Element(2), new Element(3)};

To convert this array into an ArrayList, simply use the Arrays.asList() method:

ArrayList<Element> arrayList = new ArrayList<>(Arrays.asList(array));

Example Usage

Here's an example to illustrate the conversion:

// Create an Element array
Element[] array = {new Element(1), new Element(2), new Element(3)};

// Convert the array to ArrayList
ArrayList<Element> arrayList = new ArrayList<>(Arrays.asList(array));

// Iterate over the ArrayList
for (Element element : arrayList) {
    System.out.println(element);
}
