   An inner class in Java is a class that is defined within another class. Inner classes can access the members (
   including private members) of the outer class. There are four types of inner classes in Java:
 
-    -
-        1. **Member Inner Class**: A class defined within another class.
-    -
-        2. **Static Nested Class**: A static class defined within another class.
-    -
-        3. **Local Inner Class**: A class defined within a method.
-    -
-        4. **Anonymous Inner Class**: A class without a name, defined and instantiated in a single statement.

+  - 4. **Anonymous Inner Class**: A class without a name, defined and instantiated in a single statement.
 
   Inner classes are useful for grouping related classes together, improving encapsulation, and reducing code complexity.

+  They can be used to implement callbacks, event handling, and other design patterns.
 
-Here is an example of a member inner class:
-
-  ```java
-  public class OuterClass {
-    private int outerField = 10;
-
-    class InnerClass {
-        void display() {
-            System.out.println("Outer field value: " + outerField);

   A static inner class in Java is a nested class that is defined as a static member of the outer class. It does not have
