Explanation:

In the above program, we created two classes Sample and Program. The Sample class contains a static Method Print(), and the Program class contains the Main() method. The Main() method is the entry point for the program. Here we check the specified type is public or not using the IsPublic property of Type class and printed the appropriate message on the console screen.
