Convert array to a list object using asList function

Code:: import java.util.Arrays; import java.util.List; public class ArraysWork { public static void main(String[] args) { // Strings array String cityStrings[] = {"NewYork", "Toronto", "Delhi", "Cairo"}; // Integers array Integer numbers[] = {4, 3, 11}; // List references List listStrings = null; List listIntegers = null; // Convert strings array to list object listStrings = Arrays.asList(cityStrings); System.out.println("Size of the strings list: "+listStrings.size()); System.out.println("Value at index 1->"+ listStrings.get(1)); System.out.println("Calling toString function :"+listStrings); // Convert numbers array to list object listIntegers = Arrays.asList(numbers); System.out.println("Size of the numbers list: " + listIntegers.size()); System.out.println("Value at index 1->"+listIntegers.get(1)); System.out.println("Calling toString function :"+ listIntegers); } }

The output is :

Code:: Size of the strings list: 4 Value at index 1->Toronto Calling toString function :[NewYork, Toronto, Delhi, Cairo] Size of the numbers list: 3 Value at index 1->3 Calling toString function :[4, 3, 11]
