Create ArrayList from array

Question

I have an array that is initialized like:

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

I would like to convert this array into an object of the ArrayList class.

ArrayList<Element> arraylist = ???;

Answer 1

For this code:

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

The easy way to convert this array into an object of the ArrayList class is:

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

In this, list element has fixed size which is returned from  

asList

 But, if you want to add or remove elements from the returned list, you just need to wrap it in a new

ArrayList
