Explanation / Answer

Employee.java:

public abstract class Employee {
private String name;
public Employee(String name){
this.name=name;
}
public String getName(){
return name;
}
public void setName(String name){
this.name=name;
}
public String toString(){
return "Name:"+this.name;
}
public abstract double pay();   
}

SalesEmployee.java:

public class SalesEmployee extends Employee{
private int numWidgetSold;
private double ratePerWidget;
public SalesEmployee(String name,int numWidgetSold,double ratePerWidget){
super(name);
this.numWidgetSold=numWidgetSold;
this.ratePerWidget=ratePerWidget;
}
public void setNumWidgetSold(int numWidgetSold){
this.numWidgetSold=numWidgetSold;
}
public void setRatePerWidget(double ratePerWidget){
this.ratePerWidget=ratePerWidget;
}
public int getNumWidgetSold(int numWidgetSold){
return this.numWidgetSold=numWidgetSold;
}
public double getRatePerWidget(double ratePerWidget){
return this.ratePerWidget=ratePerWidget;
}
public String toString(){
return super.toString()+"/nType:Sales numWidgetSold:"+numWidgetSold+" ratePerWidget:"+ratePerWidget;
}
public double pay(){
return this.numWidgetSold*this.ratePerWidget;
}
}

HourlyEmployee.java:

public class HourlyEmployee extends Employee{
private double payRate;
private int hours;
public HourlyEmployee(String name,double payRate,int hours){
super(name);
this.payRate=payRate;
this.hours=hours;
  
}
public double getPayRate(){
return this.payRate;
}
public double getHours(){
return this.hours;
}
public void setPayRate(double payRate){
this.payRate=payRate;
}
public void setHours(int hours){
this.hours=hours;
}
public String toString(){
return super.toString()+" Type: Hourly PayRate:$"+payRate+" Hours:"+hours;
}
public double pay(){
return payRate*hours;
}
}

SalariedEmployee.java:

public class SalariedEmployee extends Employee {
private double salary;
public SalariedEmployee(String name,double salary){
super(name);
this.salary=salary;
}
public double getSalary(){
return this.salary;
}
public void setSalary(double salary){
this.salary=salary;
  
}
public String toString()
{
return super.toString()+" Type:Salaried Salary:$"+salary;
}
public double pay(){
return salary;
}
}

EmployeeProgram.java:

import java.io.*;

public class EmployeeProgram {
public static void main(String []args)throws IOException{
Employee[] emp=new Employee[5];
emp[0]=new SalariedEmployee("ganesh",25000.0);
emp[1]=new SalariedEmployee("ramesh",35000.0);
emp[2]=new HourlyEmployee("ramarao",40.00,150);
emp[3]=new HourlyEmployee("krishnarao",37.00,160);
emp[4]=new SalesEmployee("ramu",50,150.50);
for(int i=0;i<5;i++){
System.out.println(emp[i].toString());
}
  
}
}

output:

run:
Name:ganesh
Type:Salaried
Salary:$25000.0
Name:ramesh
Type:Salaried
Salary:$35000.0
Name:ramarao
Type: Hourly
PayRate:$40.0
Hours:150
Name:krishnarao
Type: Hourly
PayRate:$37.0
