Before we wrap up this tutorial, let's take an example of the ArrayList class of the collections framework. The ArrayList class allows us to create resizable arrays. The class implements the List interface (which is a subinterface of the Collection interface). // The Collections framework is defined in the java.util package import java.util.ArrayList; class Main { public static void main(String[] args){ ArrayList<String> animals = new ArrayList<>(); // Add elements animals.add("Dog"); animals.add("Cat"); animals.add("Horse"); System.out.println("ArrayList: " + animals); } }

Java Vs. C++ ... Prior to Java 2, Java provided ad hoc classes such as Dictionary, Vector, Stack, and Properties to store and manipulate groups of objects. Although these classes were quite useful, they lacked a central, unifying theme. Thus, the way that you used Vector was different from the way that you used Properties. The collections framework was designed to meet several goals, such as −
