Homework SourseHi I need help with a java programming project specifically
Hi, I need help with a java programming project. specifically practice Program number 1 on page 662 from chapter 7 of the 7th edition of the book , java:an introduction to problem solving and programming. it tells me to define a class named employee whose objects are records for employees, it then tells me to derive the class from a class called person. it tells me that the employee record should contain an annual salary(represented as single value of type double), a hire date(that gives hired year as single type of int) and a social security number or ssn as a value of type string. My professor provided us a test program to test out both classes, but I am having a hard time figuring out how to get both classes to work within my test program.
Here is my person class
public class Person
{
public String name;
public Person()
{
name = \"No name yet.\";
}
public Person(String initialName)
{
name = initialName;
}
public void setName(String newName)
{
name = newName;
}
public String getName()
{
return name;
}
public void writeOutput()
{
System.out.println(\"Name: \" + name);
}
public boolean sameName(Person otherPerson)
{
return (this.name.equalsIgnoreCase(otherPerson.getName()));
}
}
Here is my Employee class
public class Employee extends Person
{
private double annualSalary;
private int hiredYear;
private String SSN;
//constructors which include parameters such as employee name, salary and hire date
public Employee (String initialName, double initialSalary, int joinedYear, String id)
{
super(initialName);
annualSalary = initialSalary;
hiredYear = joinedYear;
SSN = \"000-00-0000\";
}
//sets salary
public void setAnnualSalary( double newSalary)
{
annualSalary = newSalary;
}
//sets year hired
public void sethiredYear( int year)
{
hiredYear = year;
}
//set employee ssn
public void setSSN(String newSSN)
{
SSN = newSSN;
}
// return annual salary
public double getAnnualSalary()
{
return annualSalary;
}
//return hired year
public int getHiredYear()
{
return hiredYear;
}
//return SSN
public String getSSN()
{
return SSN;
}
//return true if both employee objects are the same. Otherwise return false
public boolean equals(Employee otherEmployee)
{
if(name.equals(otherEmployee.name))
if(annualSalary == otherEmployee.annualSalary)
if(hiredYear == otherEmployee.hiredYear)
if(SSN == otherEmployee.SSN)
return true;
return false;
}
//prints employee name, annual salary, year hired and ID
public void display()
{
System.out.println(\"Employee name: \" + name);
System.out.println(\"Employee salary: \" + annualSalary);
System.out.println(\"Employee hired year: \" + hiredYear);
System.out.println(\"employee ssn: \" + SSN);
System.out.println();
}
}
and here is my Employeetest program my professor provided( the big thing he said is that I am not allowed to alter this test program in anyway.
