Homework Soursedefine a class name Employee whose objects are records for e
define a class name Employee whose objects are records for employee. Derive this class from the class person given in the listing 8.1. An employee record inherits an employee\'s name from the class Person. In addition, an employee record contains an annual salary represented as a single value of type double, a hire date that gives the year hired as a single value of type int, and an identification number that is a value of type String. Give your class a reasonable complement of constructors, accessor methods, and mutator methods, as well as an equals method. Write a program to fully test your class definition
this is the test file

modify the Person class to make the test file work
public class Person
{
private String name;
public Person()
{

}
public Person(String initialName)
{

}
public void setName(String newName)
{
name = newName;
}
public String getName()
{
return name;
}
public void writeOutput()
{
System.out.println(\"Name: \" + name);
}
public boolean hasSameName(Person otherPerson)
{
return (this.name.equalsIgnoreCase(otherPerson.getName()));
}
}
this is how the input should look like. please add comments to the code.
