What are some examples of nested classes in Java?

In Java, nested classes are classes defined within another class. For example, you can have a static nested class, a non-static inner class, a local class, and an anonymous class.

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

Sure! Here's a simple example:

class OuterClass {
    static class StaticNestedClass {
        void display() {
            System.out.println("Inside static nested class.");
        }
    }
}

public class Main {
    public static void main(String[] args) {
        OuterClass.StaticNestedClass nestedObject = new OuterClass.StaticNestedClass();
        nestedObject.display();
    }
}

What about a non-static inner class?

Here's an example of a non-static inner class:

class OuterClass {
    class InnerClass {
        void display() {
            System.out.println("Inside non-static inner class.");
        }
    }
}

public class Main {
    public static void main(String[] args) {
        OuterClass outerObject = new OuterClass();
        OuterClass.InnerClass innerObject = outerObject.new InnerClass();
        innerObject.display();
    }
}
