Array is a data structure having fixed size which stores same type of elements in sequential manner. While ArrayList ,extends AbstractList and implements the List interface , supports dynamic array which can grow in size .

Situation comes when you have data in Array and you want to convert it into ArrayList. This can be done using asList() method as follows :

import java.util.*;

public class ConvertArrayToArrayList {
	public static void main(String args[]) {
		String[] states= {"UP", "Bihar", "Kolkata", "Delhi"};
		List stateslist = new Arrays(Arrays.asList(states));
		System.out.println("ArrayList of states: " + stateslist);
	}
}

OUTPUT :

ArrayList of states: [UP, Bihar, Kolkata, Delhi]
