What are some examples of nested structures in Java?

In Java, nested structures include classes, interfaces, and methods defined within other classes. For example, you can have a class inside another class, known as a nested class.

Can you give me a code example of a nested class?

Sure! Here's a simple example:

class OuterClass {
    class NestedClass {
        void display() {
            System.out.println("Hello from the nested class!");
        }
    }
}

In this example, NestedClass is defined within OuterClass.

What about nested interfaces?

Nested interfaces work similarly. Here's an example:

class OuterClass {
    interface NestedInterface {
        void display();
    }
}

Here, NestedInterface is defined inside OuterClass.

Are there any advantages to using nested structures?

Yes, nested structures can help in organizing code, encapsulating functionality, and improving readability by logically grouping related classes and interfaces.
