+  Write a program to create a class `Parent` having instance variables `id`, `name` and `address`; a class `ChildOne` having instance variables `id`, `name`, `address` and `marks`; another class `ChildTwo` with instance variables `id`, `name`, `address`, `qualification` and `salary`. Design the program using `super` call with proper parameters within each class and define your own method to display values of the member variable and use an object of each class from `main()` to display their properties.

+- `java.lang.Object` class:
+  - `Class<?> getClass()`: Returns the `Class` object representing the class of the object.
+- `java.lang.Class<T>` class:
+  - `String getSimpleName()`: Returns the simple name of the underlying class as a string.

+#skind[Classes and methods implemented in the program]
+
+- `Parent`: Base class with `id`, `name`, and `address`, displaying all information dynamically using the `display` method.
+- `ChildOne`: Inherits from `Parent`, adds `marks`, and displays them after parent data using the `display` method.
+- `ChildTwo`: Inherits from `Parent`, adds `qualification` and `salary`, and displays them after parent data using the `display` method.
+- `Main`: Creates and showcases `Parent`, `ChildOne`, and `ChildTwo` object details using the `main` method.
