Employee and Intern Classes

Create an Employee class to represent an employee of a company. The class should have name, email, age, salary properties and appropriate getters and setters.

Create an Intern class that extends from Employee. The Intern class should have a salary limit of $20000($constant$).$

Implement validation in the Intern class to ensure that an intern is not created $($or salary updated$)$ with a salary that exceeds the maximum allowed value.

Write a program that creates $10$ Employee objects and prints all of their properties $($name$,$ email, age, salary$)$ to a file named employees.txt$.$

Tips

Be sure to consider the relationship between the Employee and Intern classes when designing your solution.

Think about the different properties and behaviors that are applicable to both Employee and Intern objects and consider how you can use inheritance to avoid duplication of code.

Use appropriate access modifiers $($e$.$g$.$ private, protected, public$)$ to control the visibility of your class properties and methods.

Make sure to handle edge cases and handle them appropriately $($e$.$g$.$ what happens if an Intern object is created with a salary that exceeds the maximum allowed value?$).$
