create an object from the ArrayList class named integers

ArrayList<Integer> integers = new ArrayList<>();

// let's add the values 15, 34, 65, 111 to the integers object

integers.add(15);

integers.add(34);

integers.add(65);

integers.add(111);

// we print the size of the integers object

System.out.println(integers.size());
