Create a class called Employee whose objects are records for an employee. This class will be a derived class of the class Person which you will have to define with one data member, name. 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 int, and a UAN, which is a value of type String.
Your classes should have a reasonable number of constructors and accessor methods.

Write another class containing the main method to fully test your class definition.

Create two objects of Employee class and one object of Person class and do the following:

print all the object details
check if the Person object is the same as any of the Employee objects
check if the two Employee objects are equal

Create a class called Employee whose objects are records for an employee. This class will be a derived class of the class [Person] which you will have to define with one data member, name. 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 int, and a UAN, which is a value of type String. Your classes should have a reasonable number of constructors and accessor methods.

Write another class containing the main method to fully test your class definition.

Create two objects of Employee class and one object of Person class and do the following:

print all the object details

check if the Person object is the same as any of the Employee objects

check if the two Employee objects are equal

class Person {
    String name;

    Person(String name) {
        this.name = name;
    }
    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }
    @Override
    public String toString() {
        return "Person [name=" + name + "]";
    }
    
}

class Employee extends Person {

    double salary;
    int yearOfJoining;
    String UAN;

    Employee(String name, double salary, int yearOfJoining, String UAN) {
        super(name);
        this.salary = salary;
        this.yearOfJoining = yearOfJoining;
        this.UAN = UAN;
    }

    public void setSalary(double salary) {
        this.salary = salary;

    public int getyearOfJoining() {

    public void setyearOfJoining(int yearOfJoining) {

/*
Create a class called Employee whose objects are records for an employee. This
class will be a derived class of the class Person which you will have to define
with one data member, name. 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 int, and a UAN, which is a
value of type String.
Your classes should have a reasonable number of constructors and accessor methods.

Write another class containing the main method to fully test your class definition.

Create two objects of Employee class and one object of Person class and do the following:

print all the object details
check if the Person object is the same as any of the Employee objects
check if the two Employee objects are equal
