Thread: Help with Employee Class

Hello, I'm having difficulty with my Java code, my professor wants us to use the EmployeeDemo.java when writing our code and I can't seem to get what I am missing. Any help/tips is appreciated:

package chapter3;
 
class Employee
{
	private String setName;
	private String setDepart;
	private int setEmpID;
	private String setPosition;
 
	public Employee()
	{
		setName = " ";
		setDepart = " ";
		setEmpID = 0;
		setPosition = " ";
	}
 
	public Employee(String name, int num, String dept, String pos)
	{
		setName = name;
		setEmpID = num;
		setDepart = dept;
		setPosition = pos;
	}
 
	public Employee(String name, int num, String dept)
	{
		setName = name;
		setEmpID = num;
		setDepart = dept;
		setPosition = " ";
	}
 
	void setValues(String name, int num, String dept, String pos)
	{
		setName = name;
		setEmpID = num;
		setDepart = dept;
		setPosition = pos;
	}
 
	String getName()
	{
		return setName;
	}
 
	int getEmpID()
	{
		return setEmpID;
	}
 
	String getDepart()
	{
		return setDepart;
	}
 
	String getPosition()
	{
		return setPosition;
	}
 
public class EmployeeDemo 
{
		public void main(String[] args) 
		{	
			//creating three Employee objects
			Employee employee1 = new Employee();
			Employee employee2 = new Employee();
			Employee employee3 = new Employee();
 
			//Set all of Employee attributes 
			employee1.setName("Susan Meyers");
			employee1.setDepart("Accounting");
			employee1.setEmpID(47899);
			employee1.setPosition("Vice President");
 
			employee2.setName("Mark Jones");
			employee2.setDepart("IT");
			employee2.setEmpID(39119);
			employee2.setPosition("Programmer");
 
			employee3.setName("Joy Rogers");
			employee3.setDepart("Manufacturing");
			employee3.setEmpID(81774);
			employee3.setPosition("Engineer");
 
			//print out employee attributes on screen
			System.out.println(employee1.getName() + ", " + employee1.getEmpID()
					+ ", " + employee1.getDepart() + ", " + employee1.getPosition());
			System.out.println(employee2.getName() + ", " + employee2.getEmpID()
					+ ", " + employee2.getDepart() + ", " + employee2.getPosition());
			System.out.println(employee3.getName() + ", " + employee3.getEmpID()
					+ ", " + employee3.getDepart() + ", " + employee3.getPosition());
		}
}

employee1.setName("Susan Meyers");
employee1.setDepart("Accounting");
employee1.setEmpID(47899);
employee1.setPosition("Vice President");

You don't have setter methods likes setName("Emp Name") in your Employee class.
write setter method for each data member of Employee class like

public void setName(String name){
this.name = name;
}

and why your variable names are like setName , it's ambiguous, instead of that use some meaningful variable name like empName, empId, empDept, like wise.

Okay, this is what I've got, I dunno if it's 100% right but, now my problem is an error. The error reads

"Error: Main method not found in class chapter3.Employee, please define the main method as:

The class Employee is not the 'program' being run. The class EmployeeDemo is being run to test your Employee class; it already has a main() method, so the file you're compiling and running is the EmployeeDemo class.

There is no compilation error in your code but now your EmployeeDemo class in a inner class of Employee class and the compiler didn't able to find the main method.
close the body of Employee class before EmployeeDemo class and as your EmployeeDemo class is not an inner class anymore ,static modifier is not allowed for that class so remove it too.

and you code is ready to run.

Okay I did as you stated but, it's still throwing that main method not found error.

can you paste your modified code and the error message you get this time.

Error message:

Error: Main method not found in class chapter3.Employee, please define the main method as:
public static void main(String[] args)
or a JavaFX application class must extend javafx.application.Application

When speaking to my professor over email, he tells me they are 2 separate .java files, and that

Demo contains the main and instantiate the Empoyee class with
Employee employee1 =
new Employee();

I'm failing to understand how to get the 2 separate files to work.

Yeah he mentioned how running the Employee.Demo will use the Employee.java as a sub file. So when putting both files in the same destination folder and running the Demo.java file, I get this output:

Susan Meyers, 47899, Accounting, Vice President
Mark Jones, 39119, IT, Programmer
Joy Rogers, 81774, Manufacturing, Engineer

So is it safe to assume it is using the Employee.java as a sub file and executing correctly?

Yeah both EmployeeDemo.java and Employee.java are separate, but both are in the chapter3 folder. And after running the EmployeeDemo.java file, it did compile and execute with the output I posted. Which was:

Susan Meyers, 47899, Accounting, Vice President
Mark Jones, 39119, IT, Programmer
Joy Rogers, 81774, Manufacturing, Engineer

I'll soon find out

Thank you all for your help, I appreciate it.

Thank you.
