Live Demopackage com.tutorialspoint; import java.util.ArrayList; public class ArrayListDemo { public static void main(String[] args) { // create an empty array list with an initial capacity ArrayList<Integer> arrlist = new ArrayList<Integer>(5); // use add() method to add elements in the deque arrlist.add(20); arrlist.add(15); arrlist.add(30); arrlist.add(45); System.out.println("Size of list: " + arrlist.size()); // let us print all the elements available in list for (Integer number : arrlist) { System.out.println("Number = " + number); } // Removes element at 3rd position arrlist.remove(2); System.out.println("Now, Size of list: " + arrlist.size()); // let us print all the elements available in list for (Integer number : arrlist) { System.out.println("Number = " + number); } } }
Let us compile and run the above program, this will produce the following result −
Size of list: 4 Number = 20 Number = 15 Number = 30 Number = 45 Now, Size of list: 3 Number = 20 Number = 15 Number = 45
