My Problem is solve by saving MyInput.java file in same folder thank you to all

[atunio]

Solution: To use MyInput class you should copy MyInput.class in the same folder where u saved your file,

or learn how the import statements work. your problem was that the MyInput class was not in the same package as your main class, and you didn't provide any information to your application, that added your MyInput class to the scope of your application.
