import java.util.Arrays; import java.util.ArrayList; public class Main { public static void main(String[] args) { ArrayList myNumbers = new ArrayList(); myNumbers.add(10); myNumbers.add(15); myNumbers.add(20); myNumbers.add(25); for (int i : myNumbers) { System.out.println(i); } } } Try it Yourself » import java.util.ArrayList; class ArrayListUtilization { public static void main(String[] args) { ArrayList myList = new ArrayList<>(3); myList.add(3); myList.add(2); myList.add(1); System.out.println(myList); } } import java.util.Arrays; public class Array {public static void main(String[] args) {// Fetching Array int Arr[] = { 10, 30, 35, 52, 75 }; // Converting elements into list System.out.println("The Integer Array as a List = "+ Arrays.asList(Arr));}} Output: package com.tutorialspoint; import java.util.Arrays; import java.util.List; public class ArrayDemo1 { public static void main (String args[]) { // create an array of strings String a[] = new String[] {"abc","klm","xyz","pqr"}; List list1 = Arrays.asList(a); // printing the list System.out.println("The list is:" + list1); } } For any two non-null int arrays a and b such that Arrays.equals(a, b), it is also the case that Arrays.hashCode(a) == Arrays.hashCode(b). The value returned by this method is the same value that would be obtained by invoking the hashCode method on a List containing a sequence of Integer instances representing the elements of a in the same order.
