There are several advantages of using anonymous classes in Java:
Anonymous classes allow you to define a class and create an object of that class in a single expression, which can make your code more concise and easier to read.
Anonymous classes can be used to implement an interface or extend a class without the need to create a separate class definition. This can be useful when you only need to use a class or interface in one place, and it is not necessary to give it a separate name.
Anonymous classes can be defined and instantiated within a method, which allows you to create and pass an object of a particular type as an argument to a method. This can be useful when you need to pass an object that is only used within the scope of the method.
Anonymous classes can be used to override methods of a superclass or implement methods of an interface in a more concise way. This can be useful when you only need to override or implement a single method, and it is not necessary to create a separate class definition.
Anonymous classes can be used to define inner classes, which are classes that are defined within the scope of another class or method. Inner classes have access to the members of the enclosing class, which can be useful for encapsulating related functionality.
In summary, anonymous classes can help you write more concise and readable code by allowing you to define and create objects of a particular type in a single expression, and they can be useful for creating objects that are only used in a specific context.
