What are nested and inner classes in Java?

Can you explain what nested and inner classes are in Java?

Sure! In Java, a nested class is a class defined within another class. An inner class is a specific type of nested class that has access to the outer class's members.

What are the benefits of using inner classes?

Inner classes can help in logically grouping classes that are only used in one place, increasing encapsulation and readability.

Can you give me an example of an inner class?

Absolutely! Here's a simple example:

class OuterClass {
    class InnerClass {
        void display() {
            System.out.println("Hello from Inner Class!");
        }
    }
}

How do nested classes differ from static nested classes?

Nested classes can be inner classes or static nested classes. Inner classes can access instance variables of the outer class, while static nested classes cannot.
