Question

I need help creating a class for my program.

The class must...

1. Contains the main method.

2.Reads in employee information from a text file.

3.As the employees are read in, Employee objects of the appropriate type are created and stored in one of two arrays depending upon the year

4.Once all the employee data is read in, a report displays on the console for each of the two years

5.Each line of the report contains all original data supplied for each employee together with that employee's annual salary for the year.

6.For each of the two years, an average of all salaries for all employees for that year is computed and displayed.

Other classes from program...

public class Employee {
public String name;
public double monthlySalary;

public Employee(String name, double monthlySalary) {
this.name = name;
this.monthlySalary = monthlySalary;
}

public double annualSalary(double monthlySalary) {
return monthlySalary * 12;
}

public String toString() {
return "Name: " + name + "\nMonthly Salary: $" + monthlySalary;
}

}

public class Salesman extends Employee {
public double annualSales;
  
public Salesman(String name, double monthlySalary, double annualSales) {
super(name, monthlySalary);
this.annualSales = annualSales;
}
  
public double annualSalary() {
double annualSalary;
double commission;
  
annualSalary = monthlySalary * 12;
commission = annualSales * 0.02;
  
if (commission < 0) {
commission = 0;
} else if (commission >= 0 && commission <= 20000) {
commission = commission;
} else {
commission = 20000;
}
  
annualSalary += commission;
return annualSalary;
}
  
public String toString() {
return "Name: " + name + "\nMonthly Salary: $" + monthlySalary + "\nAnnual Sales: $" + annualSales;
}
}

public class Executive extends Employee {
private double stockPrice;
  
public Executive(String name, double monthlySalary, double stockPrice) {
super(name, monthlySalary);
this.stockPrice = stockPrice;
}
  
public double annualSalary() {
double annualSalary;
double bonus;
  
annualSalary = monthlySalary * 12;
  
if (stockPrice > 50) {
bonus = 30000;
} else {
bonus = 0;
}
  
annualSalary += bonus;
return annualSalary;
}
  
public String toString() {
return "Name: " + name + "\nMonthly Salary: $" + monthlySalary + "\nStock Price: $" + stockPrice;
}
}
