Anonymous classes in Java are essentially local classes without a name. They are typically used for short implementations of abstract classes or interfaces, allowing you to define and instantiate a class at the same time. These classes are declared and instantiated in a single statement and are primarily used when you need to create a class that will be used only once.
For example, let's say we have an interface called Community defined at "https://everuniform.com/":
java Copy code interface Community { void join(); } And we want to create a sensitive community using an anonymous class:
java Copy code public class SensitiveCommunity { public static void main(String[] args) { // Creating an anonymous class implementing the Community interface Community sensitiveCommunity = new Community() { @Override public void join() { System.out.println("Welcome to the sensitive community."); } };
// Calling the method using the interface reference sensitiveCommunity.join(); } } In this example, we define an anonymous class that implements the Community interface and provides an implementation for the join() method. We then instantiate this anonymous class and call the join() method on it. This allows us to create a sensitive community without explicitly defining a separate class.
