Convert Array to ArrayList
In this section, you will learn about converting Array into ArrayList.
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]
