expand the Employee class to have methods of get employee name, get employee sal

Question

expand the Employee class to have methods of get employee name, get employee salary, get employee ID.

Use a static variable to maintain employee ID

use my "main" program called "ObjectLab.java" but do not modify it. I will test with the base code.

Submit only the "Employee.java" file as a ZIP compression.

You must override the "toString()" method to return

Employee Name= <EmpName> Salary= <EmpSalary>

output should be this:

Name= Fred Salary= 50000.45 Employee # is 900
Name= Wilma Salary= 60000.77 Employee # is 901
Name= Barny Salary= 70000.88 Employee # is 902

File should be use:

/**
*
*
*
*
*/
public class ObjectLab
{
public static void main(String[] args)
{
Employee e1 = new Employee ("Fred", 50000);
System.out.print(e1.toString());
System.out.println(" Employee # is "+e1.getEmpNum());
  
Employee e2 = new Employee ("Wilma", 60000);
System.out.print(e2.toString());
System.out.println(" Employee # is "+e2.getEmpNum());
  
Employee e3 = new Employee ("Barny", 70000);
System.out.print(e3.toString());
System.out.println(" Employee # is "+e3.getEmpNum());
}
}

This is the Employee.java file

/**
*
*/
public class Employee
{
private String EmpName="";
private double EmpSalary=0.0;
private static int EmpNumCounter = 900;
private int EmpNum=0;
public Employee(String Sname, double dSalary)
{
  
}
  
public int getEmpNum()
{
return EmpNum;
}
  
}

Explanation / Answer

ObjectLab.java

class Employee {//Employee class

private String EmpName;//variable of empname, empno sal
private double EmpSalary;
private int EmpNum = 900;
private static int EmpNumCounter = 900;//counter for incrementing empid

public Employee(String Sname, double dSalary) {//constructor with arguments
EmpName = Sname;
EmpSalary = dSalary;
}
//getter and setter methods ofempname ,empno,salary
public String getEmpName() {
return EmpName;
}

public void setEmpName(String EmpName) {
this.EmpName = EmpName;
}

public int getEmpNum() {
return EmpNumCounter++;//incrmenting counter
}

public void setEmpNum(int EmpNum) {
this.EmpNum = EmpNum;
}

public double getEmpSalary() {
return EmpSalary;
}

public void setEmpSalary(double EmpSalary) {
this.EmpSalary = EmpSalary;
}
}

public class ObjectLab {//main program

public static void main(String[] args) {
Employee e1 = new Employee("Fred", 50000);//passing values to the constructor
e1.toString();//converting passed values in to string format
System.out.print(" Name :" + e1.getEmpName());
System.out.print(" Salary : " + e1.getEmpSalary());

System.out.println(" Employee # is " + e1.getEmpNum());

Employee e2 = new Employee("Wilma", 60000);//passing values to the constructor
e2.toString();//converting passed values in to string format
System.out.print(" Employee # is " + e2.getEmpName());
System.out.print("Salary :" + e2.getEmpSalary());
System.out.println(" Employee # is " + e2.getEmpNum());

Employee e3 = new Employee("Barny", 70000);//passing values to the constructor
e3.toString();//converting passed values in to string format
System.out.print(" Name : " + e3.getEmpName());
System.out.print(" Salary : " + e3.getEmpSalary());
System.out.print(" Employee # is " + e3.getEmpNum());

}
}

output

Name :Fred Salary : 50000.0 Employee # is 900
Employee # is WilmaSalary :60000.0 Employee # is 901
Name : Barny Salary : 70000.0 Employee # is 902
