anonymous class

An anonymous class in Java is a local inner class that does not have a name. It is defined and instantiated at the same time as a single expression. Anonymous classes are commonly used when implementing interfaces or extending abstract classes that have only one or a few methods. They are also often used for event handling in graphical user interfaces (GUIs). The syntax for defining an anonymous class is as follows:

interface MyInterface{
    void myMethod();
}

class MyClass{
    void myMethod(){
        MyInterface anonymousClass = new MyInterface(){
            public void myMethod(){
                System.out.println("This is an anonymous class!");
            }
        };
        anonymousClass.myMethod();
    }
}

In this example, an anonymous class is defined and instantiated at the same time as a single expression within the `myMethod()` method of the `MyClass` class. The anonymous class implements the `MyInterface` interface and provides an implementation for the `myMethod()` method. When the `myMethod()` method is called on the anonymous class object, it prints the message "This is an anonymous class!" to the console.
