Tip: Anonymous inner classes are useful in writing implementation classes for listener interfaces in graphics programming.
Jun 11, 2024 · In this tutorial, we’ll consider anonymous classes in Java. We’ll describe how we can declare and create instances of them. We’ll also briefly discuss their properties and limitations.
An anonymous inner class can be useful when making an instance of an object with certain "extras" such as overloading methods of a class or interface, without having to actually subclass a class. In simple words, a class that has no name is known as an anonymous inner class in Java.
Anonymous classes enable you to make your code more concise. They enable you to declare and instantiate a class at the same time. They are like local classes except that they do not have a name.

Java 9 introduced a new feature that allows us to use diamond operator with anonymous classes. Using the diamond with anonymous classes was not allowed in Java 7. In Java 9, as long as the inferred type is denotable, we can use the diamond operator when we create an anonymous inner class.
An anonymous class in Java is a local class (a class defined within a method) that doesn't have a name. It's used to create an instance of a class and provide its implementation simultaneously, often for short and simple tasks.
