Java Inheritance Use of Inheritance Inheriting Data members and Methods Constructor in inheritance Multilevel Inheritance Exercise: Create a class called Employeewhose objects are records for an employee. This class will be a derived class of the class Person. An employee record has an employee's name (inherited from the class Person), an annual salary represented as a single value of type double, a year the employee started work as a single value of type intand a national insurance number (inherited from the class Person), which is a value of type String. Write another class containing a main method to fully test your class definition. Your class should have a reasonable number of constructors (use both default constructor and constructor with parameters) and accessor methods: 1) to display all people in alphabetical order 2) to display only employees in alphabetical order 3) to find name of a employee based on national insurance number 4) to filter for employees who work for a company for more than 5 years and add 10% to their salary
OOPs
In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.
Constructor
The easiest way to think of a constructor in object-oriented programming (OOP) languages is:

Exercise:
- Create a class called Employeewhose objects are records for an employee. This class will be a derived class of the class Person. An employee record has an employee's name (inherited from the class Person), an annual salary represented as a single value of type double, a year the employee started work as a single value of type intand a national insurance number (inherited from the class Person), which is a value of type String. Write another class containing a main method to fully test your class definition.
Your class should have a reasonable number of constructors (use both default constructor and constructor with parameters) and accessor methods:
1) to display all people in alphabetical order
2) to display only employees in alphabetical order
3) to find name of a employee based on national insurance number
4) to filter for employees who work for a company for more than 5 years and add 10% to their salary
